The Merman Trapped in My Lake

Read manhwa The Merman Trapped in My Lake / 내 호수에 가둔 인어
“Serbain, why didn’t you come to see me?”
A voice called me, addressing me by the name of my great-grandfather’s granddaughter. It wasn’t a person, but a siren.
Legend has it that my ancestor, who cherished the siren deeply, imprisoned him in the lake.
What could the siren have been thinking all these years, waiting for someone who died over a century ago?
Enduring unbearable pain, day after day, without fail.
Perhaps…
“I missed you.”
…It has to be revenge. Doesn’t it?
