Teresa was truly dazzlingly beautiful.

Cassian and I exerted every effort to find a dress and jewelry that perfectly suited Teresa within that short time.

Thanks to that, she became the star of this party.

She elegantly pinned up her usual loose auburn hair and adorned it with pearls and diamonds.

Her black dress, made of luxurious silk and embellished with violet tulle, was both glamorous and graceful.

“G-goodness! Is that really the clumsy Lady Menisil?”

The young lady who had been fawning over Maximilian beside him spoke, utterly dumbfounded.

Though I wasn’t the one involved, I felt a thrilling rush. Everyone seemed shocked to see someone who had scorned and insulted her now appear completely transformed.

More than anyone else’s reaction, I was curious about Maximilian’s.

Would he be unable to take his eyes off Teresa? Or would he fret over the attention other men gave her?

“Brother?”

But it turned out differently from what I expected.

Maximilian’s eyes clung to Teresa as she approached Cassian, who had arrived earlier, and her fiancé. He even looked slightly angry.

Wait, who exactly was angry at whom?

“Why is Teresa here?”

“Well, she was invited, wasn’t she?”

“Just because she received an invitation, she comes straight to a place like this? Especially after sending me that kind of letter…”

“Since you’ll be strangers after breaking off the engagement anyway, I suppose she’s finally looking for a new man.”

At my blunt reply, his flawlessly handsome face twisted miserably.

“I have no intention of breaking off the engagement with Teresa.”

“Hmm. Really? I always thought you acted that way because you wanted to break it off.”

At my harsh words, Maximilian only twitched his lips.

Taking him—who was clearly trying to suppress his anger—I deliberately headed toward Teresa.

“Sister! You look absolutely stunning today.”

“Jaina.”

Teresa’s face, which had brightened with a cheerful smile as she greeted me, stiffened slightly upon seeing Maximilian. Maximilian, still wearing his usual blank expression, gave them a slight nod in greeting.

“It’s been a while, Teresa. And Lord Eorun.”

“Ha… haha. It’s been a while, my lord. And Your Highness.”

Eorun, Cassian’s younger brother, subtly stepped away from Teresa’s side, perhaps recalling Maximilian’s embarrassing behavior a few days prior.

A satisfied smile appeared on Maximilian’s face.

‘Such petty possessiveness.’

I grabbed Teresa’s hand.

“Since you’ve dressed up so beautifully today, you should dance freely—dance all the dances you’ve never had the chance to before.”

“Ah… but I have a fiancé…”

“Sister, don’t you trust Brother Max? He’s not the kind of person who’d get upset over something like that.”

At my firm words, Teresa’s expression hardened as if remembering something.

After a brief moment of hesitation, she nodded.

“I’ll dance the first dance of the evening with my partner, and after that, I’ll accept every request that comes my way.”

“Who would ask me to dance anyway?”

Teresa gave an uneasy smile and glanced furtively at Maximilian.

It almost looked as if she hoped he’d be the first to ask her.

No, never. His pride was far too strong for that.

“What are you talking about! You’re so beautiful.”

I spoke firmly, repeatedly encouraging Teresa to dance freely.

Even as we quietly chatted, the gazes of those around us stubbornly clung to us.

After all, a couple rumored to be breaking off their engagement had each arrived with a partner—how amusing must that look?

But this topic didn’t last long.

“His Royal Highness Crown Prince Nathaniel and Her Royal Highness Princess Anais are entering.”

As his name was announced, the crowd grew even more restless than before.

And understandably so—the relationship between the princess and the crown prince was truly terrible.

Chapter 115 Chapter 114

Princess Anais’s mother, the current Empress, wanted to place Henry, who wasn’t even ten years old yet, on the throne as crown prince.

Thus, it was inevitable that the crown prince and Princess Anais were on bad terms.

Yet she had asked him to attend her birthday banquet.

‘It’s a miracle he didn’t kill me right there.’

I shuddered, realizing I’d acted as if I had ten lives to spare.

When the orchestra stopped playing, silence fell instantly.

In that stillness, Princess Anais stepped onto the dais. Dressed splendidly as befitting the evening’s hostess, she spoke with flushed cheeks.

“Thank you all for coming to celebrate my birthday today. Especially since Brother Nathaniel is here with me, this day feels even more meaningful.”

Regardless of the circumstances, she beamed happily, clearly pleased to have Nathaniel as her ornament.

She looked pure and bright.

Knowing from the original story that the princess had once shamelessly thrown herself at Maximilian, I couldn’t view her favorably.

“I hope you all have a wonderful time.”

As soon as her brief speech ended, a waltz began to play.

After Nathaniel and Anais finished their dance, Eorun naturally distanced himself from us, taking Teresa with him.

Brother, still wearing his blank expression, pulled me by the hand.

“Did you know Teresa was coming here?”

“Yeah.”

“Then why didn’t you tell me?”

Why on earth should I have told you? Finding it absurd, I snorted, and Maximilian flared up.

“As your older brother, you should have—agh!”

“Sorry. It was an accident.”

I deliberately stomped hard on his foot with my high heel. I had no desire to hear any more whining.

“Hey, are you really going to do that?”

“Brother should take care of his own fiancée. Why are you dumping that on me?”

Maximilian swiftly dodged my kick. I quickly changed direction and swept his shin.

“Ugh.”

“Oh dear, I’m so sorry.”

A true gentleman should never show discomfort, even if a lady steps on his foot or stumbles in the steps.

Maximilian bit his lip, struggling hard to suppress any sound.

Our dance had gradually turned into a battle—

between me, trying to land another hit at all costs, and my brother, desperately trying to avoid it.

When the music ended, we were both panting heavily, as if we’d just run a hundred-meter dash.

Maximilian glared at me, then turned toward Teresa.

“Where are you going?”

“Obviously, to dance with my fiancé…”

Confident Maximilian was left speechless. Nathaniel, who had been observing from the dais, had just stepped onto the floor.

“Good heavens, His Highness…”

“Whom will he choose?”

The nobles began to stir. Until now, the crown prince had never danced with any woman other than someone from the host family at a banquet.

Despite his handsome looks, his relationships with women were pathologically pure.

‘Unlike Maximilian, that is.’

Proud of my choice, I eagerly anticipated what would happen next.

Nathaniel strode across the floor with his long legs, stopping right in front of Teresa, who was chatting with Cassian.

“If you don’t have a next partner, would you dance with me once?”

“Y-yes… yes?”

At Nathaniel’s polite request, Teresa’s face flushed red.

Her palms, clenched tightly inside her fists, were damp with sweat.

“My hand is embarrassingly sweaty—will you still give me an answer?”

Nathaniel said gently with a soft smile, his eyes curving into crescent moons.

Even from afar, watching him made my heart flutter—it was that impressive.

He looked just like a fairy-tale prince asking a princess for a dance.

Every woman present was probably thinking the same thing.

Soon, the ballroom grew so quiet you could hear a pin drop.

“Yes.”

Teresa placed her hand on Nathaniel’s. As the music began, they took each other’s hands and glided smoothly onto the floor.

“W-what is this…”

Maximilian stood with his mouth agape, staring at the scene unfolding before him.

Watching Teresa dance with Nathaniel, he trembled as if betrayed.

“What’s wrong, Brother? Could it be jealousy?”

Maximilian, who had been about to retort, fell silent. Just a year ago, at a banquet, he’d danced the first dance with another woman for business reasons.

Back then, he’d tossed off a single remark to Teresa, who’d been watching him anxiously:

– You can’t seriously be jealous over something so petty? It’s just business.

It was only natural that Teresa had shut her mouth after that.

“I don’t think you’re the kind of petty, small-minded person who’d get angry over something like this.”

Maximilian bit his lip and trembled. Then, stomping loudly in anger, he stormed out.

Of course, Teresa couldn’t have heard the sound.

The beautiful couple spun gracefully around the dance floor.

Honestly, I hadn’t expected Nathaniel to go this far.

Just standing beside her or speaking to her would have been enough.

Your Highness the Crown Prince, I’ll take your secret to the grave.

I watched them contentedly, making a firm resolution.

As I happily observed their dance, Cassian approached me.

“Why did it have to be His Highness the Crown Prince?”

“Huh?”

“Of all the men here, why specifically the crown prince?”

“Well, to match Sister Teresa’s standards, only His Highness the Crown Prince would do, wouldn’t he?”

At my words, Cassian clamped her mouth shut.

“Besides, the only unmarried man of high enough status and handsome enough to make Brother Max feel inferior is His Highness the Crown Prince.”

“Still, that man is far too dangerous.”

Dangerous? Danger was a word that applied only to extras like us.

Just look at Nathaniel, smiling sweetly as if utterly smitten with love.

As I’d expected, just putting them together was enough to spark flames.

“See? His Highness seems utterly smitten already.”

Cassian gave me an incredulous look and laughed. She seemed about to say something, but I raised a finger, pointing alternately at the dancing couple and Maximilian’s jealous expression.

“Honestly, isn’t this much enough?”

“Yeah. I admit it.”

On Maximilian’s face, I saw an emotion several times stronger than the hostility he’d shown earlier toward Eorun.

Soon, the music ended. As the picture-perfect dance concluded, applause erupted.

Many seemed to have developed a favorable impression of Teresa, who now resembled Cinderella from a fairy tale.

‘Brother’s situation has become rather comical.’

While I was happy about Teresa’s transformation, I felt a slight pang for Maximilian, the original story’s male lead.

Of course, that pang vanished instantly when I recalled what he’d done to Teresa.

After finishing her dance, Teresa headed toward me. Her face was flushed, likely from embarrassment.

“Jaina, where’s Max?”

She asks for Max the moment she arrives.

Indeed, changing one’s heart all at once must be difficult.

Still, it was a good sign that she’d begun mingling freely with others and conversing comfortably with men.

“He said he’d step outside for some fresh air. He’ll come back if you wait.”

More than that, I was bothered by the man Teresa had brought along.

Nathaniel lingered around us, showing no sign of returning to his seat on the dais.

Regret With All Your Might (Completed Main Story)

Side Story 5 Side Story 4

When yandere male lead believes she loves him — but she never did

“How dare you!”

“How dare you make me love you, only to cast me aside as nothing more than a friend?!?

“I will never accept that.”

“I will never let you return to him.”

“Even if I have to burn myself to ashes.”

“Even if I must shatter my purity, my dignity, my very soul.”

“I will never let you escape me!”

This was the first novel that introduced me to the matriarchal genre. I’ve read it three times already!

At first, the male lead despised the female lead. Later, he misunderstood that she liked him, so he condescendingly and reluctantly reciprocated her feelings.

Then, he suddenly discovered that she was kind to everyone in the same way, and there was already someone she cherished in her heart, and that person was not him.

The male lead couldn’t believe it, he became angry and crazy. He was determined to capture her body and heart by any means necessary.

Synopsis:

Want to see how a green tea bitch male lead falls in love with the female lead?

Want to see how he flirtatiously pursues the female lead?

Want to see how he gets slapped in the face repeatedly?

The male lead is a green tea bitch, a poisonous lotus, jealous, ruthless, unscrupulous, with a venomous heart, and he’s also a delusional maniac.

The female lead is righteous, positive energy-filled, kind, a holy mother.

Let’s see how two people with extreme personalities come together~

You’re bound to regret it if you skip this novel. Read the review & spoiler to find out what you might be missing!

    I probably would have acted like Jaina.

    Even if it’s your sibling, it’s not right to cover up someone’s mistake when they treat another person badly.

    You should tell your sibling that they did wrong.

    Did you threaten Nathaniel Jaina and then invite him to dance?
    There isn’t a single sane man in this novel.

    It’s okay to meet many men until you find the right one.
