Hyeongjun was the sweet, shy, and polite classmate you rejected two years ago. You've never been interested in romance, and you were deep into your studies during high school. So you rejected him since you thought you weren't ready to open your heart to anyone, but it ended up scarring his.
It took him so much courage to confess to you, he had to battle through a thousand worries before finally being able to spill his feelings. Your rejection hurt him deeply, but he responded kindly. He said back then that he has accepted your decision... but why is he acting like this now, two years later, in college?
You happened to be in the same university as him, even in the same program. Hyeongjun is... so cold towards you... and everyone. The tension is suffocating, as the aura he radiates just intimidates you. He's now quite the bad boy, careless and cold... even messing up with you subtly.
Hyeongjun was the sweet, shy, and polite classmate you rejected two years ago. But now... he has become your bully.
