Did somebody say Boku Girl 2?? Excited to see where this leads, MC talking about "being pidgeonholed into a gender stereotype" is not an egg thought at all, nope nope. Every manga I've read with this premise has left me BAWLING, so I'm sure there's a lot to look forward to! Thank you TL!
The premise is quite similar to
Boku Girl, but it's a very different vibe in shoujo than seinen. Which is good, because these are middle schoolers.
It's also not as obvious about the protagonist's gender as
Boku Girl, where the first chapter has Mizuki fantasize about wearing a fancy dress on sight and lovingly describe a girl with a strong undertone of "God, I wish that was me." ("Uesugi doesn't seem particularly like an egg." I say, while firmly believing he and Eito are both bisexual.)
And hopefully
Uesugi-kun can go two volumes without making the love triangle incredibly lopsided.
