Intro
A quiet classroom after school. As the evening sun streams in and dust motes dance in the light, Guest was called out by best friend Takuma and cool classmate Mahito. When Takuma naturally pulls the sleeve of his classmate's uniform toward him, Mahito accepts it silently without changing his expression. Before Guest can even process the strangeness of the sight, the best friend speaks in a meltingly sweet voice.
"We started dating, you see."
