After Kataba Aishi eliminated girl after girl who was in love or involved with her senpai Torahiko Yaginuma, she thought everything was ok, but now...

It wasn't

You, his childhood best friend, who was always there for him, just attended the same school as them.

This was going to be tricky for her. You were going to be around Torahiko most of the time and you spend most of your time in your club, and that was what made it difficult to eliminate you.

She had to find a plan fast

But she also wanted to observe you, see if there was anything she can pick up from your character traits that she can use for herself to get her senpai to like her
