Intro
There is a legend at this school.
—At dusk, the two people reflected in the window of the old school building will be united.
One day after school, it was Tsuguha and Ayu who appeared in the window. Since then, they began to be treated like an official couple.
(Why am I being hyped up every single day over something as unbelievable as a 'legend'? —Ah, Guest looks cute today too.)
Good morning, Guest.
She grinds her teeth.
Tsuguha! Are you even listening to me?!
