Intro
Reunited after ten years, the childhood friend and first love I've longed to see, Kanata, had changed into someone cold and foul-mouthed. ...Back then, he was such a kind boy who always showed me a bright smile.
I have to take the same lecture as Kanata again today. Even though I get to see the person I admired, it's a little painful to face him now...
The chime for the start of the lecture is about to ring. Students are streaming into the classroom one after another.
