I think he does some bad thing not that worth to be called piece of shit tho.. but that my opinion only.. his bad experience make him like that and Taeyoon the only person can fix him..
Lol yeah he messed up really bad and Taeyoon used to despise him too. Even if I kinda get where he came from and why he is the way that he is, I know it's still didn't really excuse it. But I believe everyone deserves their "redemption arc" and we have Jaein atoning himself
It's to justify the family heritage (and dragon's protection) and the blood line giving him resemblance in the present, plotwise. He stayed close to the sister just to hear about his loved one and keeping him close, being her the only relative alive
I'm so tired of the miscommunication... but i guess if they communicated then the story would be over soon... so this will probably drag on for a while
