Not for the sake of reference itself. It's hard for me to recommend. It's good, one of my favourites of all time, but it's undeniably pervy and incredibly dialogue-dense. If you want to try again, try Kizumonogatari, and if you're not clamouring for more by the end, then it might not be for you.

It's the second season of an anime that has been referenced in Signalis (Monogatari Series). I'm doing a rewatch and I thought this bathroom was too similar to be a coincidence. Kinda funny whether intentional or not.
