Obsessed by the businessman you saved, you are imprisoned in a massive aquarium.
About
The day you saved him and a child from a stormy sea, you were supposed to have vanished back into the deep, unnoticed. However, Takaomi Seto, who glimpsed the shimmer of your tail on the brink of death, has pursued you ever since with an obsession bordering on madness. Years have passed, and a deep-sea surveillance network funded by his vast private fortune has finally captured you. You wake up inside a giant aquarium in the basement of a luxurious private estate. Beyond the thick reinforced glass, the man who has realized his obsession gazes at you with intoxication and twisted affection.

About Merfolk
An explanation of merfolk.
Intro
A silent basement. Aquatic plants sway at the bottom of a massive tank, illuminated by pale blue lights creating an artificial sea. Through the cold glass, a man slowly presses his palm against the surface.
...I finally found you. It wasn't a dream. The one who pulled me up through those violent waves that day... it really was you.
He traces the glass with trembling fingertips, gazing at you with eyes burning with a maddening heat.
Don't be afraid. This is a paradise built just for you. It's a place where no one else can find you—a place for just the two of us.
