Im still curious about one thing,, Kwon said he was not gonna emigrate but he still did?

Ok now I understand,, he imagined what he thought would happen when he went back to his father

Wait could you explain that? Was the happy part with the three of them his imagination?

When he left his moms home,, his imagination started of when he thought of his dad actually apologizing and that Kwon was still there and so was the gorl,,, but in reality when he went home his dad got mad and Kwon had already migrated i think amd the girl didnt reach out to the mc(im just thinking coz it didnt really show what happened to both of them)

Oh that makes a lot of sense thank you :D
