Dazai was a teenager when he met the future love of his life Chuuya... Chuuya was the siren Prince, and he was the definition of beautiful and handsome. Dazai was the youngest prince but no one really knew he was royalty because not a lot of people spoke about the youngest prince in their kingdom, so he went undercover as a normal sailor, and explored the world.

One day he met Chuuya, who was very untrustful at first but after some time they got to know each other, Chuuya would bring things from the sea like shells and other trinkets for Dazai and Dazai would give him jewelery and other things. Years passed and they just fell in love, meeting in a hidden lagoon, since sirens and mermaids were being hunted down by other sailors, and it was only getting worse

One evening Dazai came to the lagoon as always, he didn't had to wait long before he saw Chuuya's beautiful red tail scales peak out from behind a rock. Dazai chuckled as he touched the surface of the water to create a small wave to signal his siren lover about his arrival
