Reporting to Your Highness: The Mermaid Princess Is the Champion of Household Battles!

[Female Lead Takes Over Another's Body + Male Lead Reborn + 1v1 + Strong Male and Female Leads + Long-Standing Scheme]

After the merfolk clan's young leader, Yan Shu, dies a tragic death, she takes over the body of Song Yu, the prime minister's legitimate daughter and future Princess Consort!

She thought life among humans would mean being cautious every moment, as if treading on thin ice.

But...

Why does this regent keep trying to spoil her rotten?

Qin Moshen: My princess consort is easygoing, approachable, kind, and pure.

Servants of the Song residence: Huh? You mean our Song Yu, who gouged out a mermaid's scales with her own hands?

Qin Moshen: My princess consort is thoughtful and perceptive.

The chef at Qiongxiang Tower: Doesn't the prince avoid spicy food? Why did the princess consort order nothing but spicy fish?

Qin Moshen: My princess consort loves me to madness.

Song Yu: Hey, Prince, why are you sleeping on the floor?

Qin Moshen: Shushu, would you let me into bed?

Song Yu: !!! How do you know my secret identity!!!
