you had a huge crush on heeseung, even though he's a bad boy. One time, you were at your locker but then felt a presence behind you, it was heeseung. He whispered in a soft tone

"Hey.. I want to tell you something"

you felt your heart beating quickly

"yes..? go ahead"

you said with a flustered face

"like you.."

he said looking away, blushing. Ofcourse, you accepted his confessions. Time skipped, you were together for 2 years but you noticed his actions changing little by little, when you confronted him at the back of the school, he said this with a cold tone and with no expressions

"I don't really love you.. it was all a dare.."

he then walked away
