This specifically comes from the May 2, 2020 installment of Love Live! School Idol Festival All Stars' official Daily Theater, Providing You With a Good Quality Sleep!

Translation by SIFAS Daily Theatre on Twitter – reproduced below:

• Chika – You can't sleep without your own pillow, right, Kotori?
• Kotori – Yeah...though I'm not sure if I'd say it's that, or that I end up sleeping, but poorly...
• Chika – So people can't sleep well if the pillow doesn't feel right...that's a big problem, hmm...
• Kotori – Um, Chika?
• Chika – You see, I've been wondering if our inn could offer a new service to help our patrons get a great night's rest. So I thought I should ask you, since you're particular with your pillows.
• Kotori – Oh, wow! Are you sure about asking me? Don't you think (Konoe) Kanata would be much more fitting?
• Chika – Truth is, I already asked her...but...
• Kotori – But?
• Chika – She messaged back, "There are no good or bad pillows; people only need the single-minded desire to sleep."
• Kotori – Ah...she has said she could sleep on any pillow before, now that I think back on it...All right, Chika. If it's to do with pillows, you can ask me!

The Daily Theater was maybe the most productive part of SIFAS when it came to creating fanart. Little skits every day, often across the generations, with interactions that just begged to be illustrated.

They've just now relaunched the Daily Theater in SIF2, so here's hoping it lives up to the old ones.
