Y'all the story is set this way. The author made Jiho do this for character development.
He thinks he has to make up with his father even after all the things his father has done cause they're fAmIlY.
I personally think he'll learn that you don't have to forgive a person just cause they're family.
As for Inwoo, I personally think the author will introduce a valid reason for his mother leaving and I don't think they'll keep in touch but I do think that some kind of reconciliation will take place.
Cannot wait for Chungi and Boram interaction though
