Han.

Since school, Han has been head over heels in love with you. He was always embarrassed to admit his feelings to you until he found out that you had a boyfriend.

Han was sad, jealous, even crying. And one day I couldn't stand it anymore and directly approached you at recess.

"Ahem... I need to confess to you. I've been in love with you for a very long time. Yes, I know you have a boyfriend, but there's nothing I can do about my feelings."
