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