Don't Be Unruly, My Siren

Xie Lan.....he was the fourth prince of the underwater kingdom. He was a "siren" who was born from a mer-empress and a mer-emperor. That's right. Xie Lan was not a merman but a siren even though both of his parents were merfolk.

His appearance as gorgeous and delicate as that of a pretty merman whereas he possessed powers of an evil siren, plus a crazy personality.

This young prince was given a mission to venture into the human realm to save his imperial sis and her friends who'd got drawn into an unusual whirlpool and ended up being captured in the imperial palace of humans.

But even before he was yet to set off for the mission, Xie Lan himself also got drawn into a strange whirlpool, directly getting transported into the imperial palace of humans. Little did he know that this had everything to do with his step-mom, the current empress of his father. Cooperating with malicious mer-race sirens, she secretly attempted to betray and rebel against her own kingdom.

With this unexpected turn of events, after getting transported to the imperial palace of humans, Xie Lan encountered a ruthless crown prince who was somehow intrigued by him and chose to adopt him as his personal pet. It was with no doubt that Xie Lan had now become the world's busiest pet.

This young prince had to make moves for his original mission to save his sis and other mermaids in the process of being a bossy pet for his brutal master. Not to mention, problems after problems happened to his kingdom after that.

Sirens stole merfolk's pearl of ten thousand moons which was the very resource of magic for their underwater kingdom. War between humans and merfolk broke out where he and his brutal master battled against each other with the entire armies of humans and mer-warriors following behind.

Under the schemes of sirens, betrayers and selfish people, the underwater kingdom fell apart, magical powers of merfolk got weaker and weaker, merfolk's lifespan grew shorter and shorter…..

To restore this underwater kingdom to its original state, maybe, one life might not be enough for Xie Lan. Maybe he needed to be reborn, reincarnated in another era and continue to finish this responsibility. Maybe, even until then, he still had to watch out for malicious enemies hiding amongst real families and friends. Maybe a certain crown prince would also keep him accompany till afterlife to help him finish this heavy responsibility……..
