Senti-monster Marinette Dupain-Cheng

Only She Knew

Summary:
As she walked up to the baby and picked it up, she knew exactly what to name it.

“Hello, Marinette.”
————-

An AU where Sabine and Emilie were friends, but Sabine can’t have a child so Marinette is a Senti-monster

Notes:

Everyone is like "What if Adrien's a Sentimonster"
But like what if it was Marinette who was the Sentmonster?
Sabine and Emilie were friends, and Sabine wanted a Daughter but couldn't have one, so Emilie created a Sentimonster based on the theoretical child of Tom and Sabine as a gift
(She also accidentally made Marinette be the perfect match for her son)
And eventually the effort required to sustain Marinette's existence led to Emilie going comatose

Additionally, this means we can't be sure which Ladybug was destroyed by Mayura, since they were both Sentibugs

It was a birthday today.

No, not hers. Not Gabriel’s. Not Sabine’s. Not Tom’s.

The birth of a senti-monster.

But Emilie was the only one who knew.

She crafted from scratch. She worked and worked to make the perfect one.

And today she achieved it.

As she walked up to the baby and picked it up, she knew exactly what to name it.

“Hello, Marinette.”

It was a sunny day, a few months after Adrien was born. Sabine Cheng and Emilie Agreste were in a coffee shop, chatting the day away.

“Adrien did the cutest thing today! He-” She paused when she saw Sabine’s smile fade. “Hey, Sab, what’s wrong?”

“Oh, nothing,” Sabine said. “Go ahead and tell me about Adrien.”

“It isn’t nothing. Go ahead and tell me what’s bothering you.”

“Well… I guess that it’s just… having a kid has always been my dream… and now that you have one… it just reminds me of how I can’t have a kid…”

“Oh, Sabine…” Emilie put a hand on her friend’s shoulder. “I’m so sorry… I completely forgot…”

“No. It's okay.” Sabine wiped away the tears that gathered in the corner of her eyes. “You go ahead and talk about your son. It’s only right.”

Emilie hesitated. She didn’t want to hurt Sabine, so she changed the subject. (Sabine didn’t show it, but Emilie knew she was grateful.)

As the day passed, Emilie formed a plan. One she would soon take action upon.

Minutes turned to hours. Hours turned to days. Days turned to weeks. Weeks turned to months.

She only expected one try. The single one and it would be done.
