After Mistaking My Husband for My Son

Rosalind, a witch, has been having a dream lately.

In it, a little boy calls her Mom. He's just like a genius child from a novel, knowing everything under the sun and capable in both the arts and combat. Most importantly, he's so sweet: sweet face, sweet words, sweet voice, like a little sweet-potato pie.

Her husband in the dream rarely appears, and his face is blurry. She has a bit of face blindness, so all she knows is that he's tall and strong. When his arm circles her waist, it feels as if an electric current is running through her. Trapped in the crook of his arm, she feels like prey being carefully held in the grasp of a predator.

She is completely enveloped by his clean yet intensely seductive presence, and even after waking, her heart still pounds.

It's just a normal physical reaction. She should find herself a boyfriend.

As soon as the thought crosses her mind, the sweet little boy from her dream asks her to find his father soon. She should be meeting him soon, apparently.

She wants to grant the little guy every wish.

But where should she look?

Just as she is at a loss, she sees a newspaper headline. She has never really looked closely at Gotham's richest man's face before, but it looks exactly like her little one's!

She knows what to do. She's setting off right now.

She succeeds in becoming Mr. Wayne's son's governess.

Oh my gosh! His son looks exactly like the boy from her dream! He's a little older, and their personalities are almost complete opposites. Could there be some kind of time-and-space discrepancy?

Great! He may not be her biological son, but she's got a son for free!!!

"Buy whatever you want." The little boy handed her a card.

That's right. Even if his personality isn't quite the same, her little one is still this sweet.

She took the card and leaned down to give him a peck on the cheek.

"Thank you, sweetheart~ You're just too sweet."

"Tch." He turned his head and said nothing.

"...Didn't you say I was your favorite kid?" The boy glared at her, his eyes turning red with anger.

Rosalind awkwardly set down the little boy she'd been kissing over and over.

"But he..." He's my son! I don't know how he got to this world.

Could he be my half-brother? Damian narrowed his eyes at the little boy, who was staring at him with sparkling eyes and looked so much like him.

He would find out who his father was.

How could it be himself?!

A little extra scene

"Did you go on a date with Father today?" Her son asked, frowning.

Rosalind smiled and raised an eyebrow at him. "Sweetheart, are you that interested?"

"Don't get together with him. He's a good person, but he's not right for you."

Her adopted son said it one word at a time.

"You should wait for me to grow up. I'll be grown before long."

Wait! Wait, wait, wait, wait, wait! What did he just say?!

Hold on!!! What was her husband called in the dream again???

Notes:

-OOC is my responsibility. The characters and all rights to them belong to the original creators.

-The timeline and plot are heavily fabricated, as are the characterizations. The Wayne family is involved, with some influence from the Harley Quinn animated series, plus my own take on the world. Canon purists, proceed with caution~

-A fluffy, brainless sweet romance ✓ Some logic may be sacrificed for the plot, so proceed with caution if that bothers you~

-The heroine is eight years younger than the hero. They only get together after he is an adult.

-The heroine is not a LTP, and there will be scenes of her dating other people.

Theme: The author isn't a LTP either. Seeing a real-life little boy doesn't make her shriek and run off like the Monkey King bursting from his stone egg.
