i liked yamaguchi but I think they would end up crushing at some point because shizuku doesn't really care about looks or suff like this and yamaken pointed that out various times that to be his girl she should be like that, it's true that they get along very well but still maybe too well ahah yeah haru adds flavour to her life (▰˘◡˘▰)
I'd rather choose Yamaken because I'd love being taken care and appreciated. Haru to Mizutani, it's like taking care of a childish grown man.
But I'm not Mizutani, she's all capable and serious, and will hardly ever change (that side of hers). So I think for Mizutani's case, Haru would be most compatible. He's capable career-worst, and add fun like flavors to her life. He changed her after all, and together they grew splendidly.
