Rereading this again now that the full book is translated... I still think this really sweet. I like how they come to emotionally rely on each other.
But this premise is unoriginal, and has been done better elsewhere. Your Cuteness was mentioned, and I felt that manga was a much more original take, and also felt truer to reality. Beauty standards are strict in Japan. Bullying and degendering of women, especially women of color, is common. That is what creates these feelings of "I don't deserve to be like everyone else." Your Cuteness doesn't sugarcoat that.
The prince phenomenon is real, but overtly breaking gender roles is still going to be punished. Instead we have a fantasy land here where women are encouraged to look as masculine as possible. When you look at real people IRL who were called princes in school, they never are actually that masculine, like say Utami Hayashishita.
All that is to say that examining this story in context doesn't have to make it unenjoyable. You can have two different thoughts at once. It's troubling that so many commentors here are completely resistant to thinking critically about media or acknowledging that it exists within the politics of the world around it.
If you want a very original take on tomboys and lolita fashion, and also sweet romance, try Pink Ribbon!
