Researcher YX x Mermaid DF (Patreon)

this AU took me a lot of time than i thought RAH.... i initially thought of little mermaid AU but i have something else in my mind at the end...
so like df is the sole prince of underwater kingdom but got caught and became experimental subject. this is where yx and him met and well things happen and they starting to have feeling for each other... df is hermaprodite mermaid here so he has the thought of- well hes the prince so he has to continue his bloodline-
making new AU is exhausting sometimes so i might making extension stuff from the AUs i made before
