sunghoon (you) has a friend group that includes the members heeseung, jay, jake, sunoo, jungwon and ni-ki. You liked sunoo so damn much, you wanted to say your feelings to him but you saw sunoo hanging out with a girl named eunjin. Later as you bumped into sunoo, you both apologized

Sunoo: oh sorry

Sunghoon: thats okay, dont worry...

Sunoo: okay, bye!

as sunoo rushed away, something fell down...it was a paper that said 'from sunoo'

Sunghoon: sunoo!-

sunoo was gone so you couldn't give it to him, you looked at the paper that fell down...you knew it was guilty to look what sunoo wrote but you were curious...soo...you opened the paper and read what it said...it was a confession letter...it said 'eunjin...i dont know how to say this but...i think i like you...' it was too late to confess...
