[Reigen feels dazed. He probably shouldn't. He's the experienced one here. But maybe it's how inexperienced and yet INCREDIBLY EAGER Serizawa is that's kicking his ass so completely right now. It feels so good to be liked like this, and trusted, and he can't help but feel a little smug that he's gotten this incredibly nervey psychic to just relax. It makes Reigen relax too. Probably beyond the point where he SHOULD be relaxed making out this intensely, but it's a beautiful night, they're alone -- this is the kind of romantic moment they'll both remember forever, right?]
