"in a world of machine hearts, love was the biggest capitalistic scam of them all." jung wooyoung is a globally beloved k-pop idol who doesn't believe in love. he sings about it, sells the idea of it, performs it on stage and in photo cards-but believes in none of it. to him, love is marketing. affection is currency. he drifts through a world curated for the masses,-everything is a performance. even him. then, he meets san. no spotlight. no fanfare. no filter. just a very normal office worker in a wrinkled shirt who folds receipts instead of throwing them and genuinely laughs at things that aren't even funny. someone who seems like he's living instead of just surviving. wooyoung doesn't know what to do with that. because what kind of person looks so content in a world like this?!

"The sea calls me, San. It always will." "Then I'll follow, even if it takes me to the depths." Prince San finds solace by the sea, where he encounters Wooyoung, a cursed siren bound to the ocean's depths. But as their bond deepens, the ocean's wrath threatens to destroy them both, forcing them to face a heartbreaking choice between love and fate.
