I forgot the title

Hello, it's a manga that I read a awhile back and still haven't finished, so if someone would help I would appreciate it. It's about a guy that's apparently scary and doesn't have any friends, but the main accidentally sees him at his part time job or something, which is being a power ranger, or you the actor that does the stuns. The main guy sees that he's not that scary and they become friends... That what I have read...
