Dual personality scientist x dark liar mermaid
Extreme pulling, character contrast
His blond hair was moist and smooth, and he put his arms around the man's shoulders
"Sir, don't have anyone else, just like me, okay?"
Lightning protection: Mermaids have no gender
The scientist has a genetic defect and his temperament is colder and more hypocritical
Mermaid is weak in the early stage but strong in the late stage
Purpose: Pursue the true meaning of life
