"I love you Chae." He said with his whole heart. He meant it so much, those three words aren't worth to prove the love of his life how he loves her.

"I love you too oppa." A smile escaped her beautiful face. She gave him a peck on the lips that made him scowl, wanting for more than just that. And she gave him what he wanted.

Chaerin and Jiyong had been a couple for two and a half years, tomorrow is their anniversary.

but then..

**Next Day**

"Y-you what? Are you serious Chae?!" his voice trembling in fear as Chaerin stood there keeping herself calm.

She needed to do this.

"I need to do it oppa. I have to what is ri—" before she got to finish, he cut her off.

"There you go again! Aren't you listening to yourself?! You wanted to do what is right, so is it right for you to leave me this way just because of some engagement?!"

She couldn't help it, tears flooded her eyes. She didn't know what to do anymore.

"You know we could make it through Chae, you just won't trust me." He told her calming himself. He then cried, cried his heart out. He was feeling hurt for the first time and he doesn't like it at all.

"Mianhae.."

"That's all you can say? Fine, we're through! I don't wanna see your face again! If he leaves you, don't cry running back to me, 'cause I won't be there for you." He left.

She was left their crying. She sat down and cried, thinking..

"I wish this didn't have to happen.."
