His mermaid (on hold)

"I will make you a deal.. in exchange of keeping your little secret you have to become my maid" he smirked.

Megan is a 17 years old mermaid who is a nerd, but not those goodie two shoe type.
She saved a boy from drowning when she was 5 in her mermaid form, that boy was a royal. Years went by they met again, but he is no longer the little boy she met. But what she doesn't know is what his bloodline secrets hold.
