Mutual firsts, human top x mermaid bottom

The bottom woke up.

On the day he came of age, he used his newly awakened gift of foresight and saw ten years into the future.

In a distant human star system, a tyrant unlike any before or since was in the making!

He was still as weak as an ant, bullied at will, but before long, he would grow rapidly and kill his father, mother, older brothers, older sisters, younger brothers, and younger sisters along the way!

Then, believing the rumor that mermaid blood could cure every illness, he would launch a ruthless attack on the Mermaid Empire to cure his mental instability, killing anyone who stood in his way, human or fish!

The bottom stared in horror. After much hesitation, he packed his little bundle and decided to go in person to fix the young tyrant's brain, stopping everything before it could start!

The top woke up.

The instant he accidentally ran his half-brother through with a sword, he saw a book.

The book said that the Mermaid Empire was plotting against him. After he seized the throne by killing his kin, they would send him a beautiful mermaid. The mermaid would use his charms to make him besotted, then turn on him and use his song to destroy his mental sea, leaving him completely useless. In the end, he would kill himself in agony.

That little mermaid would carry his child and run away, never looking back.

The top sized up the mermaid standing before him, bundle packed, his gaze settling on the other's stomach.

He gave a cold laugh.

Hah. Is that all?

The older brother woke up.

After dealing with a pollution incident in the distant seas, a strange voice appeared in his mind.

[Your younger brother is clever, beautiful, adorable, and kind. Everyone likes him.]

The older brother nodded calmly and elegantly.

That's right, he's my little brother. So what?

[Your younger brother has so many suitors they could circle the imperial city, but the adorable little mermaid has no interest in any of them. His suitors are frustrated and powerless.]

The older brother lifted his teacup, hiding the smile at his lips.

That's right, he's my little brother. So what?

[However, the little mermaid has been troubled by something lately.]

[That is: what should a frail, helpless, pitiful little fish do after being abducted and forced into a love affair by the human emperor?]

Older brother: ?

Wait a minute?

Where's my sword?
