I still want to understand the reason why there's two different types of arrows. Is it significant or just something random the author throws in.
I think that the different types arrows of love, are based off how they present themselves/their personality, I guess at least.
Also this is one of those rare stories where I wouldn't mind poly, but if it doesn't happen I'll die with the S.S Rinna x Mei ship. She's already stolen my heart with her cat like hair tufts, really suits her.
