So I read this manga a few years ago , It took place in high school and the story starts off in school where the uke is being bullied by some guys and the seme comes to save him . While the seme was fighting the uke sees his abs and think of fish scales and I think they start hanging out after that . I remember that in one of the chapters after that the uke starts ignoring the seme and when the seme talks to him it turns out he got a tongue piercing . The story is I think from the uke’s perspective and the uke does not show much expression on his face . I've tried to find this manga but haven't found it , If you know what it is please tell me . Thank you very much .
