Sounds like that Yuri na Watashi to Akuma na Kanojo manga, cus the "dude" needs a girl to turn back into a guy, which worries me, but if you say the ending's gay, then that sounds promising. The art's good, all girls seemed pretty cute.
When they saw the two girls who are close, I was hoping that the fox would try to pair them up tbh lmao, kindred spirits that shit. Idk if she really means to do "that" at the last page but uh, I hope she doesn't follow through.
It feels like it's gonna become a harem tbh, mc being surrounded by all these pretty girls
