I’m guessing little bro is gonna run away after kindergarten, possible go back to the old house and either 1. Think he’s truely been abandoned because MC is staying at Top’s house and doesn’t come home for a few days or 2. Sees his and his bro’s stuff still at home and hides there, everyone thinks he’s gone missing and goes on a wild chase for him only to find that he’s at their home after a couple days and maybe some big realisation from big bro and bio dad occurs.
