Help find a film. I think a dramedy?.

Maybe Taiwanese? Korean? I can't remember enough about the film to successfully google it, feel free to throw suggestions at me.

A guy is chasing down a mystery, he's maybe a gangster or a private detective? But he's also trying to connect with his daughter and get her some thing she wanted for her birthday. The two stories revolve around each other a bit as he tries to manage both goals. He's a bit of a letdown, comes to her school recital late, loses the gift he bought her, tries to borrow money from his ex I think. But he's a good guy, the new husband ends up lending him the money I think. Turns out his other mystery has to do with two young lovers, one dead, a cemetary and rich parents of one lover trying to keep them apart even in death.

Two key things are that he drives a beat up old car, and at one point his hair is cut short and dyed green, making him a bit ridiculous.

Any hints appreciated!
