He has a secret and he has no idea why. Rather than turning into a mermaid like in standard child fantasy novels, Dan Heng turns into some form of a human-dragon hybrid when submerged in water. It started around the time he started high school, and he could not find a reason why no matter how hard he researched. It's not hard to keep such a secret while at school, but it's harder to keep this secret from others, especially friends. And, it'll get all the more harder once a certain bubbly pink haired girl chooses to suddenly try to get closer to the reclusive Dan Heng. What for? Is it a prank? It is out of pity? Is it for a bet? Will he be able to hide his true nature from her? And if she does find out, will it scare her into leaving and hating him?
