Asai Kouya was a normal highschool student, but ever since he gained an F on his math test, his most favorite subject, he stopped going to school, stop caring about his health, and completely became a hikikomori.
as a hikikomori, his routine now consists of spending his time on the internet and searching up mature games to relieve his overflowing sexual urges. spending all his money on figurines of fictional girls from the anime and manga he loved, all that without him taking a rest and caring for his degrading health.
and eventually, he paid the price of his unhealthy routine and lustful behaviors as he died from a cardiac arrest after learning out that his favorite heroine in an eroge he recently downloaded is a trap. but before his death, in a cliched manner, he wished for him to be reincarnated into his eroges.
and so, he did. as he opens his eyes once again, he's given a second chance in a world similar to one of the eroges he plays, but with a catch;
for one, the world he's reincarnated into is the eroge that caused him to die in the first place,
and not just that, he was forced to be together with a pair of feminine boys, and of course in a cruel twist of fate, his heterosexuality is in danger.
TL;DR = this is a femboy heroine isekai where the protag mustn't succumb to the big gay. no homo
