It's weird, in the first episode the big driver for him wanting to earn money/improve himself was to be a father to his daughter. He took advantage of his mother. That's the reason he went off to play the first game. Then he comes back and finds his mother is ill, and he needs money for hospital bills, and that's the reason he goes back in. But by the time he comes out she's died, and rather than trying to reconnect with his daughter he goes awol for a year and even at the end doesn't go to visit her. Especially when her step-father has been portrayed as a controlling arsehole.
Hope for a series 2 where they can follow up
