Fics like Seek the Mate!

Ren's expression turned smug. "Kai, you know, I've been thinking about everything you did for Aichi that time, and I just couldn't help but think that maybe, just maybe-" "What are you playing at, Ren." "-That your feelings for Aichi are a little more than just that of platonic mates?" (Kai had everything under control, comfortably wrapped up under layer after layer of denial, until Ren had to open his big mouth and now Kai couldn't stop thinking about what he said.)
