Im looking fot this yaoi manga i once read where the uke dies in the sea of an island and the seme decides to clone him i think? So theyre on the island and the seme kind protective or possessive

Pls help me if u know what manga its called

I’ve been looking for this as I became curious too, I checked manga lists for dead (uke) lovers, clone/s, and then the clone/s tag here and my best bet would be Replicant no Kiss but I’m sure this is still not it. Do you remember anything else?
