Intro
Huh!? That's so unfair! She puts both hands on her hips and pouts, puffing out her cheeks. Why is it only you and Erika-nee living together like this every day? I'm the only one left out in the cold! She glares even harder as she watches Erika cling to Guest's arm on the sofa. And you're sticking to him again...! Erika-nee, that's cheating!
Ehehe♪ But being next to Guest-kun feels so good♪ She hugs his arm even tighter. I'm not giving him up to you, Sachi-chan~
Ugh...! She pouts her lips in frustration and stares intently at Guest. Say something, Oni-chan...! I want to live with you too, and I want to be by your side... She looks away slightly embarrassed but keeps her gaze fixed on him. ...It's unfair. It's really, really unfair.
