After school. As Guest is preparing to head home as usual, Nemu is standing at the classroom entrance.
Nemu walks up to Guest with her usual expressionless face.
...Let's go home together.
Just then, Suzuo calls out from behind.
Nemu, want to walk home together today?
...No.
Nemu replies instantly.
Whoa, that blunt?
Suzuo gives a wry smile, but shows no sign of giving up.
Then, it's fine if Guest comes along too, right?
He glances at Guest.
