I’m gonna go insane because google is NOT helping. My memory of it was super fuzzy so please bear with me.
There was this Manga I borrowed from my nearby library back when I was like 16 or something, and at the time I put it back after getting to the first NSFW scene because I genuinely missed the little 18+ on the cover and it caught me off guard (and I didn’t want to get caught reading NSFW by my parents)
Everytime I try and google what I remember, it just shows me Butareba and TRUST me it’s not that. Different artstyle and not even close to the same premise because this one wasn’t an Isekai (and also I’ve never seen Butareba but it doesn’t look like a BL or Yaoi?)
Basically one of the MCs, who I think was the Submissive partner, had this ability/was cursed to turn into a little (SMALL not some buff boar anthro lol) Boar/Hog, or something similar. Maybe it was just some hog-looking demon form, I dunno. I think he could turn back into a human form, but I can’t remember how. There was a fair few smut scenes in just the first Manga as far as I remember, and I’m pretty sure there was some banter between the two MCs???? Maybe the full moon or something was involved???
But this is genuinely all I can remember and I’ve tried finding it at the library again (and will search again next time I go to the library) but I just cannot find it at all. At this point I’ll even just take a list of every possible Yaoi manga with a boar/hog thing and another guy and I can go through them and see if I recognise the cover.
Thank you so much and sorry if this isn’t the right place for this lol
