I'm looking for a manga i read years ago. It was about a high schooler with shark teeth, i think. He had a dad who looked like a child, and his deceased mother in their picture was really muscular. I think the highschooler was somewhat attracted to the shota dad. It was a really weird but funny manga and I'm having trouble finding it again.

Could be Aoi Destruction!.

~4400 manga completed
~1700 ongoing...

That's it! Thank you so much! 😀
