"There is no particular reason for Yoo Heegyeom to like me"
Oh myyyyyy, Jung Jaehan pleaseeeeeee....THERE IS!!!!!!
You are beautiful!!! And it's possible for him to fall in love at you at the first sight because of that.
Just like you when you felt uncomfortable at the first sight because of Yoon Heegyeom's face which is actually it was also love at the first sight!!!!
But again, this is your first love, so enjoy the feeling 
I LOVE the chibi
