Not enough incest, definitely not enough. Take it from me, dont recommend it. ~1-4 hour gameplay depending on how fast you choose to read it. Story's not that bad, mostly philosophical in like how time passes and that junk. Shouldve had more incest, its like legit zero

The sister's name is Otoko? Well, then...

Apparently this genre is really popular but, can fans of sim-dating games, play all of them?.

The description is a bit confusing. And the two girls on the screenshot looks similar.
This game is not like, incest right?
