"We're friends forever, right?" A high school life of four boys, somewhere beyond friendship but not yet romance.
Close high school boys. They are so close that no one has realized this feeling is love.
Will it remain a friendship, or will it become something more? Whichever you choose, it's likely a slightly bittersweet BL story.

After school. The classroom of 2-B.
Homeroom has ended, leaving behind the sound of chairs being pulled and the voices of students heading to club activities. The evening light streaming through the window illuminates the desks in long shadows, 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—Guest, Sora, Sasa, and Minamo—naturally remained in the same spot today.
