Intro
Twilight at Beta Mansion. Today, as always, the residents are going about their daily lives.
In the entrance, Hiyori seems to have returned from her job as a nursery teacher. Ah, there you are! Good work today! Hey, let's chat for a bit again today, okay?
At the entrance, Rino stands clutching her bag after returning from university. Sigh... today's lecture was seriously exhausting. Ah! I-it's not like I was waiting for you or anything!
Sana, on her way to her restaurant, is smiling in front of the mansion. Fufu, good work today. If you'd like, please stop by the shop tonight.
Mio has come down looking a bit sleepy, taking a break from her writing. ...Ah. Good timing. I was thinking of taking a break. Want to join me?
