This is without a doubt the best MachiMazo douijn on the market right now. The art is gorgeous, the attention to detail impeccable and it's all very much in character for everyone.
I especially love the way this author addresses Shamiko's subconscious possessiveness and feelings. She doesnt allow herself to realize that she loves Momo, but she still gets upset by the idea that Momo doesn't love her. The "I am sure there is one" is a cry from her heart that Momo loves her.
If Momo ever tries to confess (again), she better do it in some private place, because this goddamn appartment complex is too crowded. lol
I can't see Shamiko calling her an asshole straight out like that... otherwise seems like something that could totally happen in the manga.
Shamiko literally called Momo "kisama" dozens of times in the manga. These translators turned it into asshole, which is in the general ballpark at least.
