I didn't like the seme at all. I get it that he wanted to wit when Hiroto was in middle school, but then when they started to live together and Wataru was ingnoring him didn't make sense at all. It was cruel of him ignoring him like that, and even dismissing his second attempt for a confession. It would have been better for Hiroto to live alone or with someone other than Wataru instead of selfishly keeping his hopes up and having him waiting for the meals if he was going to treat him like that
