What's Wrong, Poong-Sang

After graduating high school, Poong Sang got a job at a repair shop. He needed to learn how to keep his head down and lead a frugal, diligent life because he was a loving brother who had four other siblings to take care of. Even now when he is a 47-year-old man who has a family of his own to support, Poong Sang is willing to do anything for his siblings. However, his wife has had enough. When she sees her own daughter going off track, she comes to a realization.
