I Became the Regretful Male Lead's Sister (Completed Main Story) - Chapter 10
“Teresa, I know you’re deeply disappointed in me.”
Teresa’s face, glimpsed sideways, remained expressionless.
Looking at her—impossible to guess what she was thinking—my unease wouldn’t fade.
“That day, I spoke too harshly. I got angry seeing you with another man.”
He readily admitted his jealousy.
The problem was, he hadn’t expected to feel jealous of Teresa.
He hated the idea of others seeing her lovely side—known only to him—and hated even more that she’d danced with another man.
Honestly, it made him even angrier that, even in his own eyes, the Crown Prince and Teresa looked so well-suited together.
“You can call me petty. I was just jealous… I’m sorry, Teresa.”
Maximilian began trembling with growing anxiety as Teresa remained silent despite his apology.
Suddenly, it occurred to him—maybe she truly wouldn’t forgive him.
“I see. Thank you for apologizing.”
“Then can we start over…?”
“I’m sorry, but that won’t happen.”
Teresa gave a bitter smile.
If this had happened just a little while ago, she might have been moved by his apology and returned to his side.
“I no longer have the strength to stay by your side.”
“Teresa, I was wrong. Please. I’m begging you like this.”
“Why now?”
“What?”
“Even if you apologize now, it won’t erase all the pain I’ve suffered, will it?”
“Teresa, I… I’ll do better from now on, so please…”
Teresa wore an expression that seemed both like crying and laughing.
“I’m sorry, Max. I just want to end it now.”
It was a declaration like a bolt from the blue.
Did Teresa truly wish to break off their engagement?
“I hope you’ll live happily. You’ll meet someone far better than me.”
“Teresa, Teresa!”
Before he could stop her, she left the room.
Only then did Maximilian realize that it was truly over between him and Teresa.
After meeting Teresa, Maximilian shut himself up in his room. Whenever he was forced out by his father, his appearance was so pitiful it shocked even me.
He hadn’t properly groomed his beard, and his hair was left to grow wild.
‘Anyone seeing him would think he’d fallen into the love of the century.’
Anyway, six whole months passed steadily.
During that time, Father arranged his engagement to the Imperial Princess.
Maximilian had initially resisted, but after Teresa harshly rejected him, he accepted the engagement without complaint.
Worried Teresa might be uncomfortable, I only heard news of her through Cassian.
Though I regretted we couldn’t stay close as before, I found comfort knowing she was doing well.
Thus, Maximilian’s wedding to the Imperial Princess drew near.
And on the day itself.
“The weather’s lovely.”
Princess Anais, whom I’d met a few times, seemed quite kind—unlike her depiction in the original story.
I even wondered why such a woman would want to marry Maximilian.
Well, I suppose I could understand—it was because Maximilian’s outward appearance was flawless.
True to the bright weather, the wedding was held outdoors, of all places.
A cool breeze blew, and the cloudless sky above seemed to bless their union.
“Heh heh heh, welcome!”
“Congratulations, Your Grace.”
Father seemed overwhelmed by the flood of congratulatory guests.
I, too, stood beside him, merely offering a polite smile.
Trending
Just then, familiar figures appeared in the distance—none other than Count Menisil, his wife, and Teresa.
Startled, I jabbed my father sharply in the ribs.
“Did you invite them?”
“What? Would you have invited them?”
“Then who on earth did?”
Father and I exchanged wary glances, silently praying they wouldn’t come our way.
But unfortunately, they stopped right in front of us.
“Congratulations, Your Grace.”
“Oh… oh! Count Menisil, thank you for coming. Though our children’s bond was brief, surely our families’ ties will endure forever.”
“Yes. I believe so as well.”
Was it my imagination, or did I hear the Count’s voice accompanied by the sound of grinding teeth?
Anxiously, I glanced at Teresa standing beside him, her head bowed deeply.
At a glance, she was a mess.
She looked terribly gaunt, her complexion so dark it couldn’t be hidden even by makeup.
I felt an unexpected pang of guilt.
Who on earth had invited her to this wedding!
“We have seats inside.”
I didn’t want them turned into a spectacle.
“That’s alright. We’ll go to our own seats.”
But they immediately refused.
Ignoring the curious stares around them, they headed straight for the section where the nobles were seated.
Right to the center seats, no less.
“Wow, the Duke’s daughter’s family—I never thought they’d be such trash.”
Nathaniel, who’d appeared behind me at some point, muttered under his breath.
“We didn’t invite them.”
“If the Duke’s household didn’t send the invitation, then who did?”
The invitation they showed bore the Duke’s seal.
I wondered if it might have been sent by mistake, but even the handwriting matched the Duke’s.
‘Could it really be my brother, that lunatic?’
As if reading my thoughts, Nathaniel spoke.
“It seems that idiotic older brother of yours sent it—am I wrong?”
At his words, I looked toward Maximilian.
Seeing him gazing at Teresa with a face full of tangled emotions confirmed he was the culprit.
I stormed off toward the waiting room, which had only a thin screen for privacy.
“What on earth did you do, you absolute fool!”
I kept my voice low but made no effort to hide my reproach.
I jabbed a finger threateningly under my brother’s chin.
“Are you insane?”
“……”
“Why not just announce to everyone that she was your former fiancée?”
“I didn’t call her here for that.”
“Then why? To show off how happily married you’ll be—right here in front of all the nobles?”
Maximilian mumbled in a barely audible voice.
“I thought she wouldn’t come.”
“You really think she’d believe the invitation wasn’t deliberate? Would you be fine with it? Her parents came grinding their teeth in anger!”
Maximilian shuffled backward and collapsed heavily onto a chair.
Covering his face with both hands, he said nothing.
His shoulders even trembled slightly—was he crying?
Being human myself, I felt a pang of pity.
But regardless of whether he was pitiful or not, Teresa was clearly suffering.

“With a head full of flowers, no wonder you’d do something like this. Brother, please stop acting only on your own whims.”
“I just… I just missed Teresa so much. The thought that I might never see her again made it unbearable.”
Was this really the confession of a man getting married today?
My head ached.
I had changed the original story—but only the events, not people’s hearts.
Unfortunately, both Teresa and Maximilian were struggling deeply with their separation.
I began to wonder if I’d done the right thing.
Perhaps their lives and feelings were theirs alone, and by interfering, I’d left a wound that would never heal.
But what was done was done—it was time for them to go their separate ways.
“You really are trash until the very end—to Princess Anais and to Teresa. I’m ashamed to call you my brother.”
At my harsh words, he hung his head and remained silent.
Watching him like this made me feel like my chest would burst.
He should’ve listened when I told him he’d regret it!
These male leads always wait until it’s too late to regret.
You idiot!
I held back the torrent of curses I wanted to unleash and stepped outside.
Once the guests had finished taking their seats, Father was already sitting down.
Unluckily, the Menisil family sat directly behind him, leaving him visibly uncomfortable and at a loss.
I’m sorry, Father. I simply can’t sit there—it’s too awkward.
I turned quietly to slip toward the back without Father noticing.
“Jaina! Over here. Come this way.”
“Huh?”
Somehow spotting me, Father sprang up from his seat and called out.
I’d been about to leave, but ended up sitting beside Father after all.
“You didn’t actually invite that lunatic, did you?”
Here, “that lunatic” clearly referred to Maximilian.
“It seems you’re right.”
“Oh, heavens. He’s my son, but I’d like to crack open his skull and see what’s inside.”
Father stared straight ahead with a look of utter exasperation.
In the beautifully decorated hall, adorned with white and blue roses, the Pope stood ready to officiate.
It seemed true that the Emperor especially favored Princess Anais.
Normally, only the Crown Prince’s wedding would merit the Pope’s presence.
Soon, the chime signaling the start of the ceremony rang out.
As music began to play, Maximilian emerged from the back.
With his tall, elegant frame and brilliant silver hair swept back, he glided down the aisle like a scene from a movie.
Though his expression was thoroughly sour.
“Anyone seeing him might think your brother’s being sold off.”
Father whispered in my ear, grinding his teeth.
He wasn’t wrong.
But what could be done?
This was simply his karma.
Once Maximilian reached the front, Anais in her wedding gown stepped onto the aisle, holding the Emperor’s hand. Her face looked strangely pale.
Father and I mechanically clapped, praying desperately that this wedding would end without incident.
“The two of you, from this day forward…”
Wedding officiants really are all the same everywhere.
As I listened to the Pope’s long, tedious ceremony, I kept a close watch on my brother.
I was tense, afraid he might do something unexpected.
Who would’ve thought he’d actually invite the Menisil family and Teresa to the wedding.
Even as the ceremony progressed, he kept glancing back repeatedly.
Was he finally feeling remorse for having summoned Teresa?
ads
Or was it just lingering attachment?
I suppressed my anxiety and watched Maximilian’s back.
Before I knew it, the ceremony was rushing toward its conclusion.
My brother and the Princess faced each other and began their vows of love.
“Groom, will you take this bride as your partner, cherishing and loving her for all your days?”
“……”
Maximilian fell silent at the Pope’s question.
His gaze turned toward our family—and more precisely, toward Teresa, who sat behind me.
The look in his eyes, filled with desperate sorrow and pain, left both Father and me speechless.
I truly wanted to play a medley of “Cherish what you have while you still can” right then and there.
“I… “
With those words, Maximilian closed his mouth.
Behind me, I heard the sound of a chair scraping. Light footsteps—tok tok—faded away.
Was Teresa leaving the hall?
I hoped she wasn’t too hurt.
“I cannot go through with this marriage.”
Huh?
So focused on worrying about Teresa that I’d only been listening to sounds behind me, I doubted my ears.
What did he just say?
“I’m sorry, Your Highness. And to all of you.”
After giving a deep bow, Maximilian leapt down from the dais.
His neatly combed silver hair was now disheveled, and tears glistened faintly at the corners of his eyes as he passed slowly in front of me.
In an instant, he vanished from the hall.
I stared dumbly at the scene straight out of a movie.
Silence fell over the hall.
“Huh… huh! Th… that!”
The moment Father collapsed backward, the hall erupted into chaos.
Did the male lead really just flee the wedding?
Damn it!

Ex-husband Wants Reconciliation
One-line summary: Chasing the wife to the crematorium (making an effort to attract someone who has become indifferent), the female lead doesn’t look back, the second male lead takes the position.

Intro:
To repay the kindness of the older generation, Su Mu crossed into a female-dominated world and became a live-in daughter-in-law of the Yan family, single-handedly saving the Yan family from fire and water.
But her husband, Yan Jiyue, the eldest son of the Yan family, treated her with sarcasm and never showed her a good face.
It wasn’t until after Su Mu’s death that this pampered and arrogant young master shed a few fake tears and pretended to want to die for love.
This life’s kindness was enough. If there was a next life, she would definitely kick Yan Jiyue away.
Who knew that the heavens would be so kind as to allow her to be reborn, returning to the time when she had just married into the Yan family.
Su Mu glanced at the Yan eldest son, who still spoke coldly to her, and threw a divorce letter in front of him.
“Let’s divorce!”
***
Yan Jiyue never imagined that he would be reborn. He happily went to find Su Mu, wanting to make up for the mistakes he had made in his ignorant youth.
Wasn’t the reason the heavens allowed him to be reborn to let him reconcile with Su Mu?
But when he pushed open the door to Su Mu’s room, the person lying on the bed was another man.
Su Mu’s personal attendant, Xie Yi.
Yan Jiyue hated him so much that his teeth itched. In front of Su Mu, Xie Yi was a gentle and considerate whisperer of sweet nothings, but in reality, he was vicious-hearted and deliberately sabotaged their husband and wife relationship.
In the previous life, it was he who secretly hid in Su Mu’s coffin and committed suicide, stealing a step ahead of him to be buried with Su Mu.
Yan Jiyue’s eyes were filled with hatred as he cursed, “What kind of thing are you? Your background is lowly, what right do you have to occupy Su Mu?”
Xie Yi looked at the sleeping Su Mu and no longer pretended to be a whisperer of sweet nothings.
He proudly stuck out his belly, “I have the right because my belly is capable of giving the Wife-master a daughter.”
***
Yan Jiyue was consumed with jealousy. He spread rumors that Xie Yi had once been branded with the mark of a “harlot” on his chest.
But on the night Xie Yi cut off the flesh bearing that mark, Su Mu suddenly realized something was amiss.
“How did you know the exact moment I was poisoned? And why did you show up a month early?”
Xie Yi remained silent, blood from his wound soaking through his robes. His sapphire eyes brimmed with anguish – or was it just a flawless act?
Between a once-arrogant husband now seeking redemption, and a gentle soul willing to die for her – who truly held the darkest secrets? And could it be that Su Mu and Yan Jiyue weren’t the only ones given a second chance at life…?
