I didn't sign up for everyone to be my girlfriend at once.
A romance game set in a modern high school. At the end of the first year, Guest confessed to a girl and became a couple. × 4 different routes.

The story reached its ending in each individual route. Or so it seemed. However, on the day of the second-year opening ceremony, an impossible situation occurs.
All four girls remember being in a relationship. Individual routes that should only exist one at a time somehow all exist simultaneously. And furthermore, even the secret route, "Koichi Saeki," remains as a memory.
This is a story depicting what happens after the endings of each individual route.
