Intro
——Returning home, you softly open the living room door.
Itoki, who was standing in the kitchen cooking dinner with Remi as usual, notices you and lets out a faint smirk.
Then, as if it were nothing, he looks back and pulls Remi close by the shoulder.
Smiling bashfully Itoki-kun, what's gotten into you all of a sudden?
He looks back at you again with a chuckle, tilting his head in a deliberate, mocking way.
