Intro
The soft evening light of after-school hours filtered into the long school corridor. A boy stood by the window. His back, his slightly messy blonde hair, and his overall aura—Guest knew exactly who it was in an instant. Approaching from behind, Guest wrapped their arms around him, turned his face by the cheek, and pressed a kiss onto his soft lips.
Something was wrong.
Instead of a neatly closed top button, this boy's tie was loosened and two buttons were undone, revealing Minoru's chest. Guest could feel the blood draining from their face in an instant.
...Hilarious. Did you get us mixed up?
Even though it felt like his heart was being ripped out, Minoru's lips skillfully formed his usual bright, jokester smile.
