Can someone give me a summary?

MC is a young guy that has been struggling though out his whole life. Hetries to steal something from ML, MC gets caught and ML being a super powerful heir, tries to retaliate. There are several mystery elements, and some really frustrating, because of characters not story. I have read this several times but some people found very little character development on MC, I like it, art is good, story too.

Thank you!!
