As a child, Yashiro Nonoyama developed an intense fear of men due to boys constantly bullying her. Now in high school, she dreams of being reunited with her first love: a girl who protected her one day from her bullies. Yashiro is in disbelief when a transfer student named Mikoto Saionji arrives who looks a lot like her first love, but she later discovers that Mikoto is actually a guy, and that he was her first love. Yashiro learns that Mikoto is rapidly turning into a girl, and the only way to counteract this change is for them to passionately make out with each other every day.
This is a manga about a girl who is too embarrassed to admit that her first crush was a girl. Since she was a child, Yashiro has been weak and clumsy. She was often bullied by boys for how weak she was and ended up with a fear of men. Her first crush was a girl who saved her from some bullies one day. They became friends, but eventually Yashiro became so enamored with her savior that she kissed the girl, who then ran away never to be seen again. She didn't even know the girl's name.
Fast forward to high school and a transfer student
is admitted into Yashiro's class who looks strikingly similar to the girl from back then. The girl's name is Mikoto and she even calls out to Yashiro to have Yashiro show her around the school. When in private, Mikoto tells Yashiro that she remembers her and begins kissing Yashiro. In the midst of kissing, however, Yashiro accidentally touches Mikoto's groin and feels something hard, something most girls would not have.
Turns out Mikoto is actually a boy, and because of Yashiro kissing him as a child, he will turn into a girl if Yashiro does not passionately make out with him every single day. And this is the story.
The story follows their rom-com attempts at making out while keeping it a secret. The drama in the story primarily comes from Yashiro feeling as if Mikoto has no real feelings for her and is only using her in order to keep being a man. On top of that, Yashiro is still afraid of men and is horrified to find out that her first kiss was a guy.
As for the characters, I actually really enjoyed them. As dumb as some of the situations they are put in are, the characters are executed well considering how bizarre and unrealistic this setup is. The two main characters and three supporting characters are really the only important cast in the story, but they are all unique and enjoyable to read about. Some have stupid means to achieve certain ends, specifically one side character later on though. Still, the interaction between Mikoto and Yashiro is the best part of this story. Watching them grow, fall apart, and grow back together is the manga's strongest point in my opinion.
The art is well drawn and the characters are quite sexy, not going to lie about that. Mikoto may be a guy, but he is a pretty sexy trap. The story is not that ecchi, but it does have moments here and there, like one bathhouse scene that are a little more revealing, and some darker scenes towards the end of the story, though never full nudity.
Basically if you want a good gender bender manga and don't care much for the plot and just want to see some pretty good character interaction and some sexy moments between the characters, then read this manga.
Don't read it if you find rather pointless transsexual sexual moments with not much plot substance off-putting or offensive. It's not really meant to be aimed at a trans audience, as it definitely has yuri and ecchi manga fans in mind for the most part as far I could tell.
The literature featuring love polygons between girls and traps is surprisingly sparse. If you want to travel down this road, this is where you've got to make a decision; on one side, the gritty Himegoto with its wounded characters and (seemingly) realistic plot. On the other side, Yuri na Watashi, which is more of a trapsploitation flick than anything else, where the plot basically feature a girl who ends up kissing people lewdly and a trap who'll turn into a girl if he doesn't kiss his childhood love who doesn't want to but yet does it.
