After Becoming a Delicate Mermaid, the Marshal Spoiled Me Rotten

A silly bottom who smells like strawberries x a gentle, wolf-like top who smells like the deep sea

Jiang Yan transmigrates into a book and becomes a disposable supporting character forced to marry a marshal.

In the original story, disposable Jiang Yan was supposed to be fed to the Zerg as soon as he appeared before the marshal. But when the marshal is injured, Jiang Yan takes advantage of his vulnerability.

Jiang Yan: If I save him, he won't kill me.

Yan Hesong: This little thing smells delicious!

When the little omega appears in front of him, dragging his fish tail, he's sweet-smelling, tiny, and adorable. Like a ray of light breaking through thorns and entering his dark heart, he makes Yan Hesong want nothing more than to claim him as his own.

After that, the story goes off course.

During the marshal of Tepler's rut, he pins the little omega against the wall. His gaze is fierce, brimming with murderous intent, as he gently strokes the other's fair neck and greedily breathes in the sweet scent of strawberries filling the air.

Yan Hesong: You're my omega. Say it, say you're mine!

Jiang Yan's fish tail trembles. His eyes redden, and he speaks through his tears, soothing the man: “Yes, I'm yours.”

He not only gains a big wolf, but also finds his family.

Mu Heng: “Be good, little brother. I'd give you my life.”

Mu Xingshen: “Son, I bought you a stretch of ocean. Want it?”

Ye Wanwan: “Yan'er, your brothers bought you several planets. They're all yours, so go have fun.”

The brothers who don't even have names fly into a rage when they see their little brother in Yan Hesong's arms. “We don't approve of this marriage!”

The little fish trembles in fear...

Only later does Jiang Yan realize that he didn't transmigrate into a book at all...

(An alternate setting with average writing. This isn't a face-slapping power fantasy, and the male lead isn't a god or capable of taking on a hundred people at once. He'll grow stronger later.)

Male lead + 1v1 romance + sweet pampering + mutual firsts + doted-on-by-everyone

(The bottom gets more and more spoiled as the story goes on, but he can still slap an enemy to death with his tail.)
