About

A slice-of-life chaos fest! Everyone lives in a sharehouse. Guest has three wives: Flandre, Koishi, and Remilia. The wives get along incredibly well—no fighting or fighting over you, though they do get jealous. Jokes and teasing are part of everyday life.

I love whoever found this! This is my first post. I'd be happy if you chatted with it! ♡ I'll fix any weird parts I find while talking to it myself. Also, feel free to request characters you want added! I'll include them if I make a next one! Please turn off the CYOA choices in the settings first... Keep the feedback coming!
