MC may have no direction in life, or maybe think of himself as worthless, I hope you get what I mean hehe. Then someone / group of people made his life better. Basically, MC life changed for the better, something inspiring. I have a pathetic life so please haha

E.g. Punch, Plan Man

Misaeng
Horse Doctor-This drama is 50 episodes long.

I don't know if either of these are inspiring, but in both dramas the main character starts off at a low point and their lives get better.
Freeter, Ie o Kau.
Uta no Onii-san
