i don’t even remember why they haven’t been in contact for years now? can someone refr...

Cause Yeonwoon dissapear cause the monster little brother beating and family violence (his father)

Also he cut contact cus he saw ML kissing someone else(which was his step brother)

Then he completely disappears cus of additional stuff like what the other commenter mentioned. His dad and the step brother. I think he got framed for a bullying accident caused by step brother(which caused the Mom go on an anxiety attack when he saw the MC again at the hospital)
