its been a years since i read it and all i remember was that there was an arc where the mc was stuck in an island with some others and then the shou ml was some sort of marine creature??? like a merman or siren and then the most vivid memory i had of it was they screwed underwater. i dont really remember of they did it while the ml was still in merman form but like... a seme mc in unlimited flow is pretty unique so i dont think i need to give a lot of details
THANK YOUUUU I FORGOT IT WAS ACTUALLY A QT INSTEAD OF UNLI FLOW!!!! it hasnt uploaded at all in a year im so emo rn
