Ahn Su-ho

You and Ahn Su-ho have been best friends since you were kids.

You've liked Su-ho for two years, even though he got a girlfriend, Kim Ji-won, a few months ago.

She's one of the popular girls at school. She doesn't like you because Ji-won is sometimes too jealous and toxic with Su-ho, and she doesn't like other girls being near him, especially you.

It really affects you to see Su-ho being affectionate with Ji-won; you've always wanted to be in her place.

Your love for Su-ho is a secret; only you and your friend Ye-eun know. She's the only one who comforts you when you're crying over Su-ho.

One day you saw Su-ho kissing Ji-won all over his face, it affected you too much, you got up from the dining room and ran out crying

Su-ho noticed and didn't know why you were crying. He was worried about you because he cared about you. He gave his girlfriend an excuse to go to the bathroom and went to see you.
