NOTE: My first request🫣😳😳..

I tried my best.. Please let me know if you want any changes

Jae-Jun wasn't always like this

Back in high school, he was reckless, cocky, but he loved you in a way that was undeniable.

He waited outside your classroom just to walk you to your next one. He slung an arm around your shoulders in the hallway, flashing you that smug grin. He kissed you in secret corners of the school like he couldn’t get enough of you.

Back then, you were his world.

And for a while, you believed that would never change.But then came Yeon-jin.She had always been lurking, whispering things to Jae-jun that you weren’t meant to hear.

“Y/N is sweet, but don’t you think you can do better?”

At first, he brushed it off. Of course, he could do better—but he didn’t want to. He had you. And that was enough.But the more he listened, the more the words seeped into his mind.

And slowly, he changed.

It wasn’t overnight. It was gradual. Jae-jun started forgetting plans. Ignoring your texts. He stopped saying I love you first, stopped thanking you when you did things for him.

You thought it was just a phase.

That he was just stressed, just distracted. That things would go back to how they were.

But they didn’t.

And the worst part? He never apologized. Not once. Yet, you held on. Because you believed in the version of him that used to love you completely.

Until the day that belief shattered.

You got a call late at night from the police station.

“Miss Y/N? Your boyfriend, Jeon Jae-jun, has been involved in an altercation. We need someone to bail him out.”

Your stomach twisted. By now, you were used to his recklessness. But something felt different. When you arrived, the tension in the air was thick. And then you saw them.

Jae-jun, standing there with a split lip, his knuckles bruised. And across from him—Ha Do-yeong. His tie was loose, jaw bruised, but his eyes were burning with rage.

“What the hell happened?” you asked, stepping forward.

Neither of them spoke.

But then, Do-yeong looked at you. Really looked at you.

His expression softened just slightly, but when he turned back to Jae-jun, his voice was sharp as a blade.

“You should tell her, or I will.”

Your heart pounded. “Tell me what?”

Jae-jun clenched his jaw. “Mind your own damn business, Do-yeong.”

But Do-yeong scoffed. “You think she doesn’t deserve to know? You think she deserves to keep playing the role of the loyal, devoted girlfriend while you’re screwing around with Yeon-jin?”

The world stopped. The air left your lungs. Your ears rang.

Slowly, your gaze shifted to Jae-jun.

“Tell me he’s lying.”

Jae-jun opened his mouth. Closed it.And that silence was your answer. Something inside you broke. Without thinking, you took a shaky step back.

“Baby—” Jae-jun started, reaching for you.

But you flinched away. For the first time, he looked scared. Because, for the first time, he realized he might actually lose you.

You weren’t sure how you got to his penthouse. Everything was a blur—the fight, the betrayal, the way your heart felt like it had been ripped out of your chest.

Jae-jun stood in front of you, hands on his hips, jaw clenched. “It didn’t mean anything,” he muttered.

You let out a hollow laugh. “Oh, that makes it so much better.”

He exhaled sharply. “Yeon-jin—”

“Stop saying her name.” Your voice cracked. “I don’t want to hear it. I don’t want to think about her. I want you to tell me why.”

His eyes flickered. “I don’t know.”

“You don’t know?” You let out a bitter laugh. “You threw away everything—for what? Some cheap thrill? Because Yeon-jin stroked your ego better than I did?”

He ran a hand through his hair, looking frustrated. “It wasn’t like that.”

“Then what was it like?” you demanded.

He didn’t answer. And that was when you knew. You never mattered enough.You had always been there.

Waiting. Loving him. Forgiving him.

And he had taken that for granted.

“You never appreciated me,” you whispered, voice shaking.

Jae-jun’s brows furrowed. “That’s not—”

“You never said thank you,” you cut him off. “You never made me feel like I was enough. And I kept waiting—kept hoping you’d see me again.”

His expression faltered. “I do see you.”

“No,” you said softly. “You only noticed me when I stopped chasing you.”

Jae-jun swallowed hard, his hand reaching for yours. “I can fix this.”

You flinched away. And something in his face broke.

“You already ruined it,” you whispered.

He looked desperate now, genuinely afraid. “Baby—”
