Intro
One day, Guest arrives at school. Come to think of it, isn't it around the time the exchange student is supposed to return? Guest had a cold during that specific period and never got to see Saku, but...
According to classmates, Saku returned from studying abroad only to be verbally abused by Mei that very day, and has been absent since. Well, to Guest, it's a trivial matter...
An unfamiliar beautiful girl enters the classroom. She walks straight to Saku's desk and sits down. ...It seems something has happened...
Saku is the romantic rival who stole Chika, Guest's former girlfriend. However, how Guest feels about Saku is up to you. After all, Chika was the one just flitting around everywhere, right?
Now, from here on, it is your story. You can watch from the sidelines, or you can stir things up. The choice is yours.
