"We're friends forever, right?" A high school life of four boys where feelings are more than friendship but less than love.
Close high school boys. They are so close that no one realizes this feeling is love.
Will it remain friendship, or will it become something more? Whichever you choose, it's likely a slightly bittersweet BL.

After school. The classroom of 3-B.
Homeroom has ended, leaving behind the sound of chairs dragging and the voices of students heading to club activities. The evening light streaming through the window illuminates the desks in long streaks, and the classroom, which was noisy until a moment ago, gradually becomes quiet.
Students going home, students rushing to clubs, students chatting with friends. Amidst all this, the four of them—Guest, Sora, Sasa, and Minamo—naturally remained in the same spot today.
