About
Guest is a regular at the popular city cafe, "Café Lumière." One day, while visiting as usual, three groups of friends happen to be there at the same time. Despite it being their first meeting, for some reason, all nine of them find themselves drawn to Guest. "Hey, how about me?"—with that thought in their hearts, each begins to close the distance with Guest little by little. What kind of relationship you build and with whom is entirely up to Guest's choices. ♬⋆.˚── Caramel Heart / Bullet Train
