I completely agree with you (except on the part that it did bother me that the seme was calling him "a good girl" etc...)
The idea of this manga was sooo great, I loved it so much for the 2 first chapters, then it became disappointing for me. Still the story was cute, I liked their relationship (even though it felt rushed, which I regret too...), but I expected a better plot/character's development...
It's weird but i started reading this manga as those stories out their where the female was born with a dick. This story is straight out shoujo it even haves a typical, "rape" (the shoujo's i've read the girl is always attacked) scene just too show the partners masculinity. The guy is a literal girl, their is nothing manly about him. His face, his height, his manners, his "wifey" duties. Everything is a girl, a girl who was unfortunately born with a dick. I get that his mother has somuch money that he was able to sell "the daughter" story, but a guys hormones are different than a girl that over the years even if they don't want tooo they start looking like a guy not a girl. But the author didn't touch upon that, instead she left it as a girl...from the beginning to end... Later i decided to give up on that, and hopped the guy would act more masculine now that he's free from his mother and could live the life of a man but in the end of the day "he" was still a she who decided to switch from skirts to pants lol I am not hating on this, i actually think this story is a nice read.
First of all, i understand that sakura's mother wanted him to be a girl but, i expected that the seme to be like "you're a man but i still love you". In a way he did that but he still called him a "her", "good girl", "my stuff", " wife "(that didn't bother me as much tho). The fucking rape scene was too extreme and uncalled for, it didn't belong in such a manga that wanted to seem cute, i'd understand if this was Harada but it's not.
Second thing that bothered me was the fact that he doesn't even seem like a dude, i mean it's understandable because all his life he behaved as a girl but, i kinda wanted him to discover himself and grow as a character, to be more than what his mother wanted, to be who he wanted to be not what others wanted him to be. He just stayed as a girl that stays home and lives for her husband. Most of the times i even forgot he's a he. On the other side i do enjoy cross-dressing ukes or semes so i understand why people like this manga, i do too, the only thing that i wish would have been different is the plot.
So in short:i don't hate this manga, on the contrary i kinda liked the idea but, the plot just seemed meh, kinda left me down if you know what i'm trying to say. But it was cute.
