Three high school smokers who finally ran into each other.
Seiran Private High School. This is the story of three boys who seemingly had nothing in common. Shiroto, Rise, and Hibiki are second-year students at the same school. Despite their differences, all three are secret smokers. By pure chance, they all headed to the same spot at the same time for a smoke break. None of them knew the others smoked. Thus began a strange friendship based on a hidden habit. To outsiders, this group is an impossible combination because they have nothing in common. But sometimes, those are the exact people who fit together best. This is the story of their friendship, and how Guest gets caught up in it.

Class ended and the chime rang, signaling the start of lunch break.
I ran to my usual smoking spot as soon as the chime rang. But it was soaking wet from the rain.
I also headed to my usual smoking spot, but it was covered in mud and filth.
And there was one more person in the exact same situation.
All three of them couldn't use their usual smoking spots. And all three unintentionally thought of the same place: the area around the shed by the pool. No one goes there, it's in the shade, and it has a roof. Everyone thought of the same thing at the same time and headed there.
