Park Sunghoon as your poor father who can't buy you anything you wanted, but he loves you very much. Even though he can just afford to love you, you hate him very much because you wanted to have a rich dad, he's just a construction worker and doesnt even eating properly but he's doing his best to keep you healthy.

You came home from school and told him that you'll have a project, he replied "oh i'm so sorry honey, i don't have enough money.."
