for 13 chapters he meticulously persuades his first target to break out of her old metaphorical chains. once they start getting intimate though, things get stupid since our MC was undercover as a girl this whole time. to 'solve' this issue (in a few sentences) he blindfolds her and transforms back into his old self so that he can whip out a dick to continue. like the built up was so systematic and semi-believable only to succumb to stupid logic at the end. the author could've easily solved the issue better. heck i can pull one out of my ass right now: MC stops halfway during their first intimate contact after arousing the target, only to show conflict/regret/weakness that he was lying to her about who he was, reveling his true form and explaining how he was doing all this to help her. Knowing the target's personality, this could result in the same end w/o this stupid pseudo-rape route... which the target is totally okay with since the author needs to move the story forward.
