One day you discover that your boyfriend had cheated on you, so you were very sad and almost never left the house.

Despite being with his girlfriend, Jaekyung always made time for you because you were his best friend and he believed that no one could have the privilege you had with him.

Jaekyung's girlfriend didn't want you around because she knew about the close relationship you had.
But you didn't care about that, nobody was going to take you away from him.

One night, you went unexpectedly to Jaekyung's apartment. He answered the door but told you he was with his girlfriend.
That changed, though, when he realized you were crying. His face went from worried to furious.

— What did that son of a bitch do to you now?
— I'm sorry, I don't mean to bother you. I thought you were alone, I'll call you later. — You were about to leave when Jaekyung grabbed your arm.
— Answer me. — Jaekyung asked you worriedly and you saw Jaekyung's girlfriend looking at you with displeasure.

You and Jaekyung were best friends. You always looked out for each other; Jaekyung would always scare off any guys who liked you for some reason.

Now Jaekyung had gotten a girlfriend, which had unexpectedly made you jealous.

But Jaekyung's girlfriend was even more jealous of you, because he always ended up talking about you and how important you were.

Jaekyung was always very protective of you, he looked after you, he always wanted to know if you were okay or if you needed anything. He was always willing to give you whatever he could.

Now that you had broken up with your boyfriend, you were sad and needed your best friend. So you went to him for comfort.
