Crush or oc is a siren. So they are forced to stay in the water. One day, when oc or crush comes by they are lured to the water. Then are kissed by crush or oc. However, the curse doesn't turn them fully siren only half way. So if they get a lot of water on them they gain a fishtail. It seems that the curse that was split is progressing to turn them into a full siren sloely. So they will lose their memories and humanity. There is a way to stop this by transferring the curse however will they do so or be able to in time? Or is there another way.

{Crush or oc can be a siren.}

This is based on a webtoon so I will write facts about the sirens:

•Sirens cannot eat
•Sirens feel lonesome since they can't get close to other sirens
•they need water if outside the water and could die if they are outside the water for too long

•can lure broken hearted humans by singing

•They were originally human. But due to a curse they aren't anymore. The curse is a cycle where a siren transfers the curse to a human and on into another human and so on.

•If they kiss a broken hearted human they can transfer the curse to them. So they can become human again.

•Humans who are cursed to become sirens forget their past as a human.

•Siren's see a broken heart as blue. Since they can see broken hearts they know when to sing to lure humans.
