The Heroines Always Invite Me to Talk All Night

I was reborn in this world with my memories intact.

I thought it was a modern-day world with supernatural powers, but it turned out to be the world of an 18+ adult game.

The good news: the heroines fit their roles perfectly.

The bad news: it seems a little too dangerous to have all of them fall for me at once.

My brilliant adopted younger sister, who's been accepted into an elite school through a special recommendation and is obsessed with her big brother, turns out to be a leader in an official organization.

The generous widow next door, who keeps asking me to fix all sorts of things, turns out to be a snow woman.

The school belle, who suddenly gains the power to stop time, has designs on me. If I refuse to go on a date, she'll strip me and dump me in the street.

Even the decorative sword I bought before turns out to be a cursed blade inhabited by a demon sword maiden.

... (Skipping a thousand words)

Around here, classic scenarios are always popping up, and if I'm not careful, the girls will pounce on me.
