Comment by 백나겸 on Love is an Illusion! - Superstar - Chapter 9

@백나겸 That's because Hyesung was bad in school except for math. Until he went back again as an adult!

@karasu hime was he actually bad in school or just not street smart (can't rmr)

@Lyssa He was actually bad because of low self esteem etc but always good with math, but that he kept hidden and I can't remember why.
