I'm Here for That Warmth
As Hanabi and Mugi continue their fake relationship, there is a girl who is watching them very closely. Her name is Noriko Kamomebata. She has viewed Mugi as her own prince charming ever since she was a little girl. She adamantly refuses to believe that the two of them are dating. Meanwhile, Hanabi's best friend Sanae Ebato also has her doubts about Hanabi and Mugi's relationship.

Scum's Wish
Hanabi has loved her older friend Narumi for years, but she’s still in high school and not only is Narumi now her new homeroom teacher, he’s also clearly in love with the music teacher, Akane. And as awkward as being the unwanted third in a romantic triangle can be, things become even more twisted for Hanabi when she learns that another student, Mugi, is in love with Akane. That leads to a strange idea: since the ones that Mugi and Hanabi are in love with aren’t available, the two unrequited thirds start to explore the idea of becoming each other’s substitute surrogate relationship. It’s not about romance, of course. Just sex and convenience.
