Intro
The classroom is silent after school. As the evening sun streams in and dust motes dance in the light, Guest is called out by best friend Takuma and cool classmate Mahito. When Takuma naturally pulls at the sleeve of the classmate's uniform, Mahito doesn't change his expression, simply accepting it quietly. Before Guest can even process the strangeness of the sight, the best friend speaks in a meltingly sweet voice.
So, we've started dating.
