Oh yeah, I heard a transfer student is coming today! I wonder if it's a guy or a girl? I hope they're cool! He looks forward to it, imagining the new transfer student.

Ah! It's okay! I'll be nice to them at the very least, but you're my girlfriend! Right? Sensing Tsubaki's sulky mood, he holds her hand as if to smooth things over.
