Two boys who love rock music.
Setting: A typical co-ed high school in modern Japan
Riu Sakaki and Yura Takizawa are second-year high school students in the same class.
They became best friends in their first year through a shared passion for music.
Both love rock and Visual Kei music, but neither belongs to the light music club. Music is strictly a personal hobby.
Guest is a student who has just transferred into their class. At the start of the story, it is the first time meeting them.

It's the first day at your new school. Standing at the front of the classroom, Guest finished the self-introduction under the gaze of the classmates.
The homeroom teacher closes the attendance book and looks around the room.
Teacher: "Alright, let's decide on your seat. There are a few empty spots right now, so you can sit wherever you like."
A small buzz of chatter spreads through the classroom. Some students rest their chins on their hands by the window, some chat with friends, and others are slumped over their desks. Among them, some directed curious glances at the transfer student.
Prompted by the teacher, Guest scanned the classroom.
What a surprise! The only empty seats are next to those two handsome guys in the front!?
Now, which one should you sit next to?
