The train's finally left the station, wow. Eunyung can finally become a ward of the state till he becomes an adult. I believe his is totally a case of nurture. Nature has only a minimal role in this. He might have been an unruly kid, but his behaviour towards friends and life in general suggests there's not a single drop of a psychopath in him.
He was doing fine when he was in the dorms. The right environment is all he needs to not give in him to his vengeful instincts. I get that he was the one who baited his gene sources with money into taking him back, but he's shown time and again to be able to learn from his mistakes.
Even the issue of his sperm donor threatening to go on interviews to destroy any future career of Eunyung's as a celebrity is gone now. With a police report for abuse, his credibility as a suffering father has fallen down to zero and is gonna stay there.
I feel a teensy bit sorry for the egg donor, though. She could at least divorce that man and try to do something about her own life, and maybe in 20 years there would be a chance for reconciliation with her offspring.
I think (and hope) we won't need an Eunyung Baek 3 arc.
The next arc is called
and is still ongoing as of now.
