My Beautiful, Utterly Foolish Mermaid Wife

[Two Male Leads + Custom ABO Setting + Sweet, Adorable Romance + 1v1 + Happy Ending] [Hot-tempered, domineering researcher gong × silly, beautiful, fiery-tempered mermaid shou] Liang Chang is out at sea when he accidentally catches a stunning little mermaid with golden hair and blue eyes.

Don't leave me, please~ * Once Liang Chang understands his feelings, whenever the little mermaid cries, he holds him close and patiently soothes him. When the little mermaid opens his mouth and says “I'm hungry,” Liang Chang willingly lowers his neck and offers his gland to the mermaid's lips. He spoils him without limit. But as the research progresses, misunderstandings begin to arise...
