This is an app designed by the Millennium Engineering Club - it lets you see how many times you can do it in a day after marrying your teacher~

Aru: Just what is that app and how does it even work?!

Haruka does it once every 3 days, and Aru goes 4 times a week, you know~

As for Kayoko-chan -

Aru-chan, Haruka-chan, look at this.

Mutsuki: That's amazing.

Aru: Uwah, this is...

What? What results came back?

Haruka: Eeeeh?! Manager Kayoko...you're kidding, right?

By the way, since I only do it once a day, I win.

How can you get so excited over such a silly thing...

Haruka: I wonder if S-Sensei will be okay...

Aru: Sorry, Kayoko, I've been underestimating you all this time.

Just how many times in a day is it, anyway?!

I-it really knows?

Mutsuki: There's a saying... "Don't judge a book by its cover," right~?
