I saw your comment on "Mine to Love" and Trust me... i loved it. I can't say there because author thought I am actually disrespecting the story but trust me, your comment made me feel I am not alone who felt that.
JK'S character actually worsened, and most important I feel sorry for his daughter. Taehyung now loves his daughter and family most burdening himself with all but the way JK got happy when Taegguk was born and loves him from day 1 contradicting the situation with Jenella who was abandoned already due to JK'S tight Scedule now at 1½ was totally forgotten by Jungkook. I agree that he cares but the favouristm shows when he calls sweetly to Gguk and strictly to Jenella.
And most important he was ready to abort Jen but when Gguk was actually the mistake he was naming he didn't let him go. Says a lot!
