One plus one is sometimes three

In which Anzu has a crush.
And is definitely not living with them.

(In other words I'm finally getting around to how copyshipping actually started.)

I just keep lifting my titles from song lyrics, so if you're interested, this time, the title of the fic (not the chapter) is from Sing you Home, a song accompanying Jodi Picoult's novel by the same name.
I took some liberty with it since the song is about waiting for a baby and not welcoming a third person into your relationship, but since both are technically a part of this story, I think I'm fine. :P The novel is, sadly, one of the books that kind of ruined Jodi Picoult for me, because of its recurring (and unchecked) biphobic moments, but I still like the peaceful, domestic-fluffy vibe of the soundtrack. It has a kind of exciting-and-unexpected-but-still-familiar air that I'm imagining for these three, as well.

I'm still easing into the whole polarshipping dynamic, so once again I am taking major pointers from Jien, this time from her headcanons for Kasuya's and Mai's first date.
