Guysss I forgot does she know what he went through?

Yea

Thx

Partially, he didn't go into detail (he told her he was bullied to the point of wanting to kill himself but not about the sa)

Thank youu i was curious about that

Yeah. Yeonwoo confessed but just partially. He probably didn't want to tell Haesol what they actually did to him in fear that she might be disgusted with him if she found out. Which is kind of sad just how low of an opinion he has of himself. When it comes to Haesol, he is resolve to like her regardless of her past. But when it comes to himself, he believe he's not good enough for Haesol to look pass his own past.
