The story was cute until it dawned on me that he rescued a 10 maybe 11 year old boy in hopes of a relationship is weird dude. He raised he's lover. He was at his old ass age looking at a pre teen and probably reminiscent of how he fuck older Alois, that last few panels of them laying together with Alois being so young is ugh, because you can't deny that the duke is inlove with the kid. Pedophilia is not necessary to make a good story, BECAUSE THAT'S WHAT THIS IS
I'm not a fan of Serizawa's character. He's quite an aloof character even with Katou and there's only a slight change into their relationship. But that's he's character I guess
