I LOVED! very cute, comic and a little erotic for a shoujo, it would be more for a josei, but even so after seeing 4 generic manga with absurd plots and unreasonable characters, this raised my spirits.
Nako I think has been one of the best protagonists of shoujo, not only because she is emotionally very strong, she is determined and with a lot of determination, despite being very pure and innocent. That shy combination and her sadistic awakening, even takemoto shuddered, even me, seeing how she gives everything of herself to be more selfish in order to conquer Futaba.
Speaking of Futaba, I SEEMLED A GARBAGE CHARACTER, I understand that he has a complex because of his unusual orientation, but he was an asshole from the beginning, being submissive (M) is not synonymous with being an asshole who only runs away from being hurt and not seeing How much the protagonist loved him and did even what not for him, just because he wanted not to stain her? I don't think he noticed very well that she is very strong and determined, even though he said so himself.
A heroine with well placed ovaries, undoubtedly one of my favorite shoujos, romance, with a touch of eroticism, I'm not a big fan of BDSM, but seeing how they did something cute I just loved it, outside of the trash boy who finally became yielded, the protagonist is to remember.
