[Rin is smug and pleased, as he watches Haru's expression; really, he had absolutely no chance -- who could resist a fish as cute as the pipefish? and that's not the only exotic fish in his arsenal, either. of course, he'd flipped through the book one last time the night before to familiarize himself with it, just for an occasion that might arise just like this (where he could show off and be right and maybe beat Haru at something, like who was the bigger jerk)]

[but then of course, Haru throws off all his plans with dumb, embarrassing questions, and Rin gives a startled, nervous laugh]

What are you asking that for? You know it's different with people versus fish, right? Fish don't date, or fall in love, or anything...

[this is embarrassing. he hates Haru. he should have just shown him the most poisonous, creepy looking one, but he'd wanted charming, and now here they are, with Rin explaining the dokidoki facts of life, and how they have nothing to do with Finding Nemo]
