Sometimes I like poly ships, some other times I can't help to think the third and so-on girls are getting in the way of my ship. This is the latter.
I think Dia x Sarah would make a nice ship but not many people seem to care.
Tbfh not gonna lie, I wouldn't mind Kougi being the only ChikaRiko artists. Their art is absolutely cute and amazing. They're actually one of the reasons why I actually like ChikaRiko now :x
