This anime's OP is super interesting
>No manga translations
>No LN translations
Why can't we have nice things?
>Perverted guy (MC) wants to be able to express his emotions better
>equally perverted friend becomes nonperverted by wishing his impure thoughts away at the Stony Cat statue
>MC goes to cat, runs into girl (one on the left in OPs pic) that wants to be more like an adult and able to hide her emotions
>They wish at the cat
>MC can't lie
>Girl is emotionless
beyond that is spoilers
also, series is known as HenNeko (Hentai Oji to Warawanai Neko, literally "The 'Hentai' Prince and the Stony Cat")
I actually liked the ending. It´s conclusive and
best girl wins.
