So yeah, now I'm pretty sure that either the girl friend or the guy friend will, at some point, clearly show to the MC that they won't really love him/her if he/she were to stay androgynous (or if he/she chose the incorrect sex for them) and they will automatically become hostile to the MC and vice versa and then *boom* - auto-win for the other friend or maybe even for the doctor instead, assuming both of them would react to his/her choice negatively.
Seems to me like this will be around as predictable as that and that there will be tons of pointless drama and over-dramatization of stupid stuff (assuming it won't be a really short series like some of these are), but I guess the ride might be kinda fun nonetheless.
Guess I'll stick with this one. For now.
