Taegyongs relationship with the rest of the Gong fam was never good because of blood relations but in the end the family basically bullied Junha to give up his daughter because Yeondu didn't want him in Haneul's life. Yes, he was prideful and obsessed BUT all he wanted was the right to raise his own child and they hated him for it. It made no sense to me. Could they not have done a colaberative effort of raising her and letting her know her dad, mum and stepdad instead of the no-contact dad storyline?
