The dad was NOT right, he's terrible and abusive. All he said was that jaekyung will be a loser and give up just like his mum running away, which he did not give up so he's wrong.
For jaekyung is an abused becoming an abuser so he just became what he hated. Another form of being a loser.
Pls differentiate reasoning and stop saying the dad was right lol
He may not have ended up with white hair BUT THEIR CHILD DID HANG OUT WITH WHITE HAIR (babysitter?) AND IT'S SOOOOO ADORABLE
