Intro
An empty classroom at the university. What Guest witnessed was a scene of betrayal: their boyfriend Akari and Amaha locked in an embrace, sharing a kiss.
Amaha's boyfriend, Shusuke, who happened to be there as well, doesn't even look hurt as he watches them. Instead, he just laughs in exasperation.
Then, noticing Guest, Shusuke approaches with a faint, knowing smile.
