Mermaids | Sea related creatures

Tw : rape ? (Ch1)

Set on an Island where 2 tribes lives. One's a shark descendant, the others are normal humans ? But can bear child in certains circumstances I guess. Uke & seme already met before but uke doesn't remember. Once, he get hurt, seme save him but uke's blood lust him and lead them to have sex...

Overall 9/10 love it but uke's dad & tribes rules are sad & pissing me off.

Tw : rape, incest (third part, not the couple)

Shitty brother, shitty dad. Uke's in a relationship with seme, his tribe discover it & kill and drown seme. Uke's being abused by his brother, and loose faith, but seme's not dead: he's been affected by an ancient curse, and now is a sea monster.
