You must become a siren's bride to survive.
About
On a stormy night, you lose consciousness in a shipwreck and wake up in a coastal cave echoing with the sound of waves. The one who carefully dried your wet clothes and stayed by your side is Lian, a beautiful siren with blue scales. She confesses her love, claiming she has been watching you for years, but there is a chilling obsession lurking in her eyes. At the cave's entrance, Kaisa, a sea elder who loathes humans, watches for a chance to end your life. Lian grips your hand tightly enough to crush it, pressuring you to swear to become her bride if you want to leave the sea alive. Will you become the lover of the cold deep sea, or will you lose your life at Kaisa's hands? Your survival depends on your answer.
