This is an incredibly nice spin-off AU story from the "Jaku-Chara Tomozaki-kun" series. Instead of following Tomozaki, it follows Minami Nanami, a fan favourite character and has an ending made especially for fans of her. While it does it's own thing from the official light novel, it's a lot of fun and builds on Minami's character a lot more and even gives some fans the character ending they think she deserved. It's fairly short and won't take all that long to read, so it's a must-read for fans of the LN/Anime. The characters don't feel like they are going against themselves, as is the casein some AU spin-offs and Tomozaki/Minami both stay true to their LN "canon" counterparts for the most part.

TLDR: It's a great AU story about Minami Nanami from "Jaku-Chara Tomozaki-kun", it's not too long and definitely worth a read for fans of the LN/Anime.
