Teresa could not understand Maximilian.

For a long time, staying by his side, she too had gone through much.

She saw him attend banquets with other women, breaking promises to be with someone else.

Sometimes, he didn’t even remember his promises with Teresa.

That was fine.

She loved him and believed that if their positions were reversed, Maximilian would understand her too.

“How can I trust you? You reject my invitations, my letters, and say you need time?”

“I trusted you. I trusted you every time you met another woman instead of keeping our promises, every time you danced the first dance with someone else.”

She believed that by doing so, he would open his heart to her.

Teresa still remembered the words he said the day they first met as fiancés.

– I don’t know if I can love you, but if you trust me, I’ll trust you to the end.

So she put all her effort into trusting him.

“Do you think I’m deaf? I’ve heard all the rumors you’ve spread, even the ones about us. But Max, I didn’t believe them because they didn’t come from your mouth.”

“That, that’s…”

“I trusted you no matter what, but Max, you can’t trust me.”

The passion in Teresa’s eyes cooled in an instant.

Seeing this vividly with his own eyes, Maximilian realized that if he didn’t act, their relationship would end.

“Teresa, I!”

A hand reaching over the wall brushed the hem of Teresa’s dress.

“I’m sorry, Max.”

“What?”

“The promise to stay by your side forever and protect you—I don’t think I can keep it.”

Had there been such a promise?

Maximilian couldn’t understand what Teresa was saying.

Why couldn’t she keep the promise?

“It’s not your fault. I… I don’t think I can endure anymore. I’m sorry.”

“Teresa! Wait, just wait a moment!”

Maximilian tried to climb over the wall to run to her but tripped and fell to the ground.

Normally, Teresa would have turned back to ask if he was okay, but she disappeared into the darkness without looking back.

Maximilian, unable to stand, could only watch her retreating figure.

For some reason, Nathaniel was sitting by my side.

It was uncomfortable, but I couldn’t speak harshly to my benefactor.

“Someone’s coming.”

At his words, I turned my gaze and saw Teresa approaching.

Her eyes were red, and her expression was stiff.

A bad feeling crept over me.

The end of their relationship might not be as good for Teresa as I thought.

“Uh, Teresa…”

“I’m sorry, Jaina. I won’t be able to stay in touch for a while.”

I couldn’t say anything to her as she briefly greeted me and left. Nathaniel shrugged and left the spot.

I told Cassian to go to Teresa and then searched for Maximilian.

“Where is that guy?”

I found Maximilian not far away, standing with a dazed expression.

“Brother! What did you say to Teresa?”

At my question, Maximilian looked at me as if waking from a spell.

“Where’s Teresa?”

“She said she was leaving and went away. What did you say to make her cry?”

“Teresa was crying?”

“You were just with her!”

Maximilian was acting as if something had short-circuited.

He didn’t seem to be in a good state.

“Let’s go back to the ducal residence for now.”

“…”

I grabbed the silent Maximilian, who was staring at the entrance, and dragged him outside.

With the coachman’s help, I forced his large frame into the carriage, sweating from the effort.

“Let’s go!”

I told the coachman and climbed into the carriage.

Even in the carriage, he remained silent.

‘What’s wrong with him? Did she say she’s breaking up?’

In the original story, Maximilian was the one who demanded the breakup.

Saying he wasn’t sure he could love her, giving absurd reasons to force the breakup.

Thinking of the words he said to the pleading Teresa made me furious.

It seemed like they had fought, but I decided to pretend I didn’t know.

From now on, it was their business.

The next afternoon.

Father called us to his study.

Maximilian looked haggard overnight.

“The Menisil family has formally requested to break the engagement.”

“What?!”

I shouted before covering my mouth. Then I immediately turned to my brother.

His face was calmer than I expected, but his lips were trembling.

Had he never imagined Teresa would want to break the engagement?

“Since we haven’t prepared for the marriage, I plan to settle it with appropriate compensation.”

“That’s absurd! Why should the Menisil family pay us compensation?”

Maximilian did all the bad things, Teresa was hurt, and now the Menisil family has to pay?

That was too unfair.

“Jeni, they’re the ones who requested the breakup.”

“But it’s because Max tormented Teresa!”

“Jeni!”

“You know it too, Father. How coldly Max treated Teresa. Even people from our household, instigated by others, harassed her.”

At my words, Father closed his mouth, looking guilty.

If the harassment of Teresa by the ducal maids became public, things would get complicated.

“Max, what do you think?”

The duke’s gaze turned to the silent Maximilian.

He, who had been quiet, finally spoke.

“I don’t want any compensation.”

“Hmm.”

Why is he suddenly saying something reasonable?

“There’s no need to break the engagement either.”

“Max, what do you mean? They’re willing to take all the losses to break it off… Isn’t that what you wanted?”

The duke looked confused by Maximilian’s words.

So was I.

Has he lost his mind after being dumped?

“No. I’ll convince Teresa. Please wait until then.”

With that, he stood up abruptly and left the room.

Father and I, left alone in the study, muttered to ourselves.

“Could it be your brother was serious about Teresa?”

“Well… I just found out myself.”

It was truly baffling.

From that day on, Maximilian visited the Menisil estate every day.

He was turned away almost every time.

Today, he came back soaked, as if he’d been doused with water.

Father looked at Maximilian disapprovingly.

“Tch. If you liked her, you should’ve treated her better, you fool.”

I was quite surprised by Father’s reaction.

In the original story, he wasn’t pleased with the engagement to Teresa.

Since the family’s status had risen since the engagement was made, it must have felt like a regrettable match.

“Father, didn’t you dislike Teresa?”

“What? What kind of man do you think I am?”

‘A cold noble who only calculates family benefits?’

I kept that thought to myself.

The characters’ reactions were a bit different from the original story. Come to think of it, Teresa also acted differently, so there must be things about the others I don’t know.

‘Did I oversimplify things?’

I had a bad feeling.

Unaware of my thoughts, Father looked at the drenched, sighing Maximilian and said,

“Your mother and I didn’t get along well. That’s why I wanted my children to marry for love. Look at what your brother’s done. I thought he naturally disliked Teresa.”

“Well… that’s true.”

Father’s unexpectedly sincere response touched me. So he wasn’t a cold-blooded man after all.

“But if Teresa doesn’t change her mind, what will you do?”

“Well, we’ll find a suitable match and send him off. That fool doesn’t know what he has.”

Wise words.

I wanted to contact Teresa right away but decided to hold off for now.

Seeing Maximilian’s state, I wasn’t sure my letter would reach her safely.

The Menisil family might throw away any letter with the Winters name.

‘But I can’t just sit still.’

If a long engagement breaks, both sides lose, but Teresa, as a woman, would lose more.

In the original story, Teresa was branded as a hysteric.

She was insulted and despised everywhere she went.

Already timid, Teresa grew more withdrawn, with many sleepless nights.

‘Stress is the root of all ailments.’

I quickly wrote a letter to Cassian.

I suggested gathering people who rarely interacted with Teresa for a tea party.

Especially women with unfaithful husbands or fiancés with mistresses, who had suffered heartache.

Rumors tend to spread further and louder the more you empathize with the victim.

Arriving at the Velicia estate, I took a deep breath.

The tea party was probably in full swing inside.

‘The protagonist arrives late.’

Smiling brightly, I told the butler to announce my arrival.

“Miss, Lady Jaina has arrived.”

“Oh, please come in.”

Cassian’s acting was more awkward than expected.

That girl is really bad at this.

I vowed never to make her do it again and greeted the people inside.

“Hello, everyone.”

“Welcome, Lady Winters.”

Perhaps because they were mild-mannered, they didn’t seem too wary of me.

We chatted while eating cookies and drinking tea.

“By the way, Jaina, you don’t have a fiancé yet. Is there someone you have in mind?”

Feeling more at ease, Cassian’s acting became more natural.

I lowered my eyes slightly, let out a long sigh, and said,

“As you know, my family’s been in an uproar over marriage issues.”

“Oh… right.”

“Yes. It’ll be troublesome until the young duke’s issue is resolved.”

Everyone offered sympathetic words. As if waiting for it, I began to complain.

“Exactly. I kept telling my brother to treat Teresa well.”

The reaction was immediate.

Hearing a story slightly different from what they knew, they all looked intrigued.

“That kind Teresa couldn’t stand my brother’s behavior.”

“Oh my.”

“Well, the young duke was overly friendly with other ladies.”

A noblewoman who had long been dissatisfied with Maximilian’s behavior said, glancing at me.

“Exactly. Everyone says my brother is the best groom, but I don’t think so. If I were Teresa, I’d be so angry. Thinking about it makes marriage a bit scary…”

“Yes, the young duke was too indifferent to his fiancée.”

They started chiming in one by one.

Seizing the moment, I delivered the final blow.

“Once, when I was with Teresa, I saw him escorting another lady. I was so embarrassed.”

Everyone gasped, mouths agape.

Then they shared similar experiences from their past.

Their anger erupted in an instant.

“That’s too much!”

“Miss Menisil put up with that?”

“Goodness, how much she must have suffered.”

Fortunately, they united in condemning Maximilian.

They’d probably go home and nag their husbands and fiancés about this.

I wanted Maximilian to bear the full disgrace of this broken engagement.

Regret With All Your Might (Completed Main Story)

Side Story 5 Side Story 4

Male lead Asks for a Divorce Every Day

It’s not often you come across a plot like this in the female-dominant genre — make sure to check it out!

This is a novel I’m planning to reread as well.

The male lead is strong, skilled in martial arts, and not the usual fragile type you often see in matriarchal novels.

Meanwhile, the female lead is a scientist—rational and logical. Even when she falls for the male lead, she doesn’t let her emotions cloud her decisions.

If you push through the first few chapters, you’ll gradually find the story really intriguing.

It has a mix of mystery, detective elements, and romance.

The author’s writing style is like crafting a puzzle—except they deliberately leave out a few pieces, making it hard to predict what happens next, yet keeping you hooked.

In the end, everything will come together and be explained.

One-sentence summary: Wife, stop playing with beakers and look at me!

In a laboratory accident, research scientist Zhu Wansheng accidentally travels to a matriarchal world. The original owner of the body is an eighteen-year-old only daughter of a wealthy rouge merchant, already married with a handsome young man.

Zhu Wansheng grins: Nice! She always said she was heaven’s favorite granddaughter. After a life of toil in her previous life, she can enjoy blessings in this one.

However, her joy lasts no more than three seconds as bad news arrives: the original owner’s family is about to go bankrupt, and her husband wants a divorce.

Even worse, she’s stuck with a research system full of restrictions.

Zhu Wansheng: ? Is this the destiny of a research dog?

——

Faced with this mess, Zhu Wansheng pours herself a bowl of wine to drown her sorrows. In her drunken haze, her husband arrives.

His figure is imposing, holding a long sword, with a dignified air that captivates Zhu Wansheng.

Gu Yingqing, however, looks at the alcohol-reeking Zhu Wansheng with undisguised disgust and coldly asks, “Divorce or not?” The intoxicated Zhu Wansheng mumbles vaguely, “I think… it’s not… it’s not… impossible!”

——

The next day, after sobering up, Zhu Wansheng is full of energy, rolling up her sleeves ready to make a big move. As for yesterday? She has no memory of it.

Zhu Wansheng is ambitious; a research dog fears nothing!

Upgrading rouge, extracting fragrances, producing perfumes, researching lipsticks… all shall bow to the power of modern technology!

The original owner’s dying rouge shop is revitalized. Her mother is pleased and with a wave of her hand, passes on the family business to her. As she takes control and her experimental results gain popularity, it’s the pinnacle of her life…

——

But there are always those who can’t stand to see her doing well. Jealousy, scheming, assassination attempts – they want nothing less than her life.

The person who has always kept his distance from her suddenly holds her tightly in his arms, eyes full of concern.

She is unharmed, but he falls into a pool of blood…

Zhu Wansheng feels guilty, “I can grant you one wish.”

Gu Yingqing tentatively circles his arms around her, carefully resting his head in the crook of her neck, pleading softly, “I regret it. Can we not divorce?”

Zhu Wansheng: ? When did I agree to a divorce?

[Small Theater]

The newly developed rouge is beautifully packaged, and Zhu Wansheng is eager to try it.

Gu Yingqing suddenly appears: “My lady, may I apply it for you?”

Cool fingertips lightly brush her lips. His Adam’s apple bobs as he leans in for a light bite.

Zhu Wansheng: ?

Gu Yingqing: It smells so good, I wanted to taste it…

On a warm spring day, Zhu Wansheng tries a new perfume: “Spring Night.” Gu Yingqing corners her against a wall.

Warm breath lingers on her neck.

“My lady, from now on, may I test the fragrances for you?”

    The Empress is truly vile and disgusting; she doesn’t think about what her children want, but rather controls their lives and imposes her will upon them.
