he felt guilty and i assume his dad died? im not sure anymore
He had PTSD from the car accident which can cause things like suicidal and negative thoughts
beside what the other comments have said already, they haven’t seen each other in a while, and by what we could see, his personality at the start was different from what it is now, and he looked like he was mostly alone. Not having the support you need can be really damaging
his cousins (at school) n family were kinda spreading rumors about him too, saying he’s the reason their family business (the cousin’s) went down n why the accident happened in the first place. he was young so he kinda believed it for a bit. it wasn’t until he met the mc that he started growing out of that.
Naaaur his dad didn't die, his parents just got divorced. Remember it was shown on one panel, the mom and dad was arguing. Ig author nim diddn't delve much on Yeonwoo's family drama.
Why tf did he try to commit suicide then? He's family is very wholesome, tf?
