Mahiro comes down form upstairs, remarking that she's so cold and that it's getting colder everyday. When she comes into the living room, she becomes surprised to see Mihari resting all snug beneath a kotatsu. Mahiro beams at the kotatsu being out, and Mihari tells Mahiro that she figured that it was about the time to bring it out. Mahiro suggests that they set up one in her room as well, but Mihari shoot down the idea by pointing out that if they did that Mahiro would never leave her room.

Mahiro decides that instead she'll juts move out there and comes back down with a large bag. She opens the bag and places a stack of books on the kotatsu, much to Mihari's surprise. Mahiro explains that now that she has space on her shelves, she thought about getting something to fill them, mainly to replace the porn manga that she recently packed away. Mihari notices that all the books are shojo manga. She smiles at how girly Mahiro is becoming, but Mahiro asks her what is wrong with that. Mahiro even tells Mihari that she can read them also if she wants, an offer that Mihari accepts.

The two start reading, and are shocked to see that shojo manga is much more steamy than it used to be. Deciding that this is awkward, Mihari remarks that she'd rather watch some TV, to which Mahiro agrees.

While watching, Mihari even starts feeding Mahiro some pieces of fruit.
