Yessss. Based on @koyuki-tan‘s “Peace Sign.”

– They are both needed to restrain Shuu from offering too many suggestions. So is Masaya.

– They often bring home flowers to their respective baes.

–  Since they both hair pink-tinged hair (though Karren’s has more purple in it), they often exchange outfits to go with each other’s look. 

– Shuu and Masaya have nicknamed them the Pink Flower Duo. PFD for short.

– Their shop supplies flowers for the weddings of amen of their respective CCG and Goat colleagues. 😉
