I think you'd like this one it's Blue Period it's about this high-school guy that doesn't know what he wants to do in life. He's a delinquent that has good grades but doesn't know what to pursue. He finds painting and then his life goes on. It's a very slice of life thing. A lot of relatable experiences and encounters of maturity and growth. I really like this one. It's also going to have an anime soon this fall. It's in black and white though so I wonder if that's fine.
