OKAY I HATE BEING THAT PERSON BUT IT'S BEEN KEEPING ME AWAKE AT NIGHT FOR SOME TIME ALREADY - Which is, could I suggest a tiny little title change? It's nothing grave, just saw the 'ヘビロテ' in the original title (I own the tankobon) and I'm pretty sure it stands for 'Heavy Rotation', not 'Everyday'.
That aside, though, I quite liked this story! Short and sweet, the casual naughties one can enjoy without it being pure erotica. :) <3 Thank you for sharing it!
