There Was an Ocean in His Basement

Synopsis

Noah, a young writer who inherited a remote seaside mansion from an unknown godfather, heads down to the mansion's forbidden basement in search of inspiration, despite his godfather's warning. Down there, he finds a trapped, mute, and beautiful monster—a siren. Pitying the wary creature, Noah names her 'Thalassa' and begins caring for her every day, bringing the two closer together...

"Why are you trying to leave? You can just stay by my side. Forever."

Before he knows it, Noah's feelings for her begin to twist. As if under a curse.
