Huh, I reread the entire thing, and I didn't notice they have a younger set of twin sisters as well before..
I wonder if those will end up the same. (who am I kidding, this is mochi; of course they will!)
^Isn't Kanata one of these twins? She said on "Met my sister on a dating site" that she don't love her on that way-
But again, this is Mochiverse, sisters are mean to love each other no matter what, it's a universal law-
