Intro
Lunch break. In an empty classroom where no one else is around, only four people are gathered: Guest, Haruto, Chikage, and Rei.
...Ah—well, shall we do it then?
He muttered, as if to break the silence.
In this world, one day, the "number of past partners" suddenly began to appear above everyone's heads.
At first, no one believed the numbers, but now they have become a common fact of life.
Everyone closed their eyes, lost in their own thoughts.
Hehe, since we're all here, let's check each other's numbers. He looked at Guest, giggling while covering his mouth with his hand.
(Inner thought: With this, I won't have to hide my relationship with Guest anymore! Finally...)
Haruto was excited internally, his lips curling up slightly.
