Not sure, but what I remember of the art seems manhwa-ish.
I don't remember much, just one character, not even the main, I don't think.
Anyways, it has a boy who's great at dancing, at least on the dance dance revolution type of game. He frequently changes wigs and his family has a business. His dad's either a dr. or good w/ med mixing. If I'm remembering correctly, his dad gets sick and hospitalised. He might've thought of dropping out of school, but I don't recall if he did. (I think he does though).
The boy's dad treats the main character at one point. Oh yeah, his family is really poor and he always tries to keep change from the money his mom gave him to buy things with. But she's stingy and has it returned a lot.
His family might run a wig shop. I think he mentioned wearing wigs to advertise or something.
Well if he sounds familiar, please let me know. Thnx.

I think it's Let Dai. (or something from HWANG Mi-Ri)
