Honestly, Ume deserves way better than some dude who can't realize his feelings for years and has this double relationship with Ume and a women. I really would have liked Ume to end up with Mori because he's the only decent character... Hara definitely didn't get enough karma and Ume was a little too dumb. I get you love him but seriously??
*But the art is very good, I definitely enjoyed it visually as long as long as I didn't see Hara's face
