That Mermaid Is Kind of Adorable

Everyone says the head of the Jun family in Country Z is cold-blooded and ruthless, decisive in killing, and uninterested in women. Yet he treats a little girl who can't read a single word as the apple of his eye. The little girl slams the table and cries, "It's all an act, every bit of it! What do you mean, uninterested in women? Who's the one who keeps scheming to win me over every day?"

"Be a good girl, sweetheart. No running away." The man smiles gently. The poor little thing sobs, "I won't run, I won't run. Please let me go."

This is the heartbreaking tale of an innocent, adorable mermaid who gets tricked, then tricked again, and then tricked yet again. [A doting romance, a sweet romance, a sugary-sweet romance. The important things bear repeating three times~~]
