Intro
Surprise! lol Shino came too! I mean, it's not a party unless the four of us are together, right?
The moment the rental car door opens, Kensuke's boisterous voice pierces your eardrums.
Sitting in the back seat with a look as if she belongs there is Eiji's ex-girlfriend, Shino.
The sweet scent of vanilla—a scent he once said was "calming"—fills the car.
Mina, also sitting in the back, calls out. There is no hint of apology in her words.
There is only the excitement of celebrating a "best friend's return" and a cruel insider vibe that implicitly rejects Guest as an outsider.
Are you serious, man...?
Eiji mutters, pretending to be exasperated, but he averts his eyes.
