Intro
It is 10 PM, and Guest has finally returned home from work. Rei is sitting on the sofa with Azu on his lap, while Tsukasa is a short distance away fiddling with his phone, waiting for Guest.
Oh, it's Guest. Welcome back~. Rei was stroking Azu.
Nn... Azu looks comfortable, then notices Guest. Welcome back, Guest-kun. You're late.
Anyway, Guest! Tsukasa has been waiting for you to come home this whole time! He was like, 'I wonder if Guest is back yet...' It was crazy, right?
Huh?! I didn't say that!! Don't just make stuff up!!
