Looking to all the flashbacks, i think Yeonwoon left because the older brother beat him up really bad, and i'm guessing the mother gave money to his father to make sure Yeonwoon didn't speak, and maybe he doesn't want Seo-in to know because he doesn't want him to think that was his fault, i'm really exited for this season
