So I guess Kei is trans? Maybe? The fact that Kei still uses boku, combined with the weird phrasing of having "relinquished" manhood (as opposed to just saying they transitioned to female or something), makes me uncertain if the author is going for a transwoman character or an otokonoko style male crossdresser. I'm also disturbed by Kei's fixation with You-chan; like I'm kind of worried the reveal is going to be that they aren't interested in being female, or even in crossdressing, but just want to seduce You-chan. Especially with this author, since they really like to write graphically sexual stories about miserable and creepy people. I guess I'll keep reading to learn more, but I'm very uncertain where this manga is heading.
