The Invisible Sister (MLB FF) (Adrien/Chat Noir x Oc)

Volpina

Macy POV

It has been a week since our first date. The very next day Mr Agreste called Adrien back to the Agreste Mansion saying he had to go somewhere for a shoot. 

The days have passed by quite slowly. I asked Alya to promise not to say anything about our dating to anyone in school until Adrien and I talk about it, so nobody knows about us yet. I decided to speak to Adrien and keep our relationship under wrap for a little bit. 

Marinette and I have finally started getting along and... I don't want this to get in between that.  Despite everything that happened, it was more of my parents' fault than hers, and I'm willing to start over. 

I'm sure Adrien would understand. After all, Mr Agreste may object to this too, which would cause too many problems.

Rolling over, I finally decided to get up and go to school.

Walking in, I was surrounded by talk of something called Lila knowing a bunch of famous people from all over the world. 

She seems to know prince Ali, Jagged Stone, Hollywood directors and, to my surprise, Princess Magic. 

Lila seemed to be the one who wrote the lyrics for my hit song, which is funny cause that song was more about my life experience so it was just:

aaaaaaaaahhhhhhhh *inhales* aaaaAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHH

I shook my head, instantly realizing how big of a liar she was as I went inside. That's when Alya came to a screeching halt in front of me. 

"Mace! have you heard of the new girl Lila?", She exclaimed. 

I nodded hesitantly, "I heard rumours...". 

"Turns out, she was once saved by Ladybug! her interview helped my blog blow up!", Alya smiled widely. 

"That's great!", I smiled back half-heartedly, "So where is this mystery girl?". 

Alya's face lost its initial colour as a slightly awkward atmosphere surrounded us. She slowly pointed upstairs, where Adrien stood, next to a brown-haired squirrel-like girl who was obviously flirting with him. She began taking his hand, leading him into the library. 

What...?

The boy hasn't even come home after returning, yet he's already getting girls left and right. 

Stomping forward, I made my way to the library, standing behind the closed doors as I peeked in and listened to their conversation. I saw Marinette also peeking from behind a shelf and let out a small puff of laughter. 

We're not sisters for nothing.

Little did I know. The real reason my sister was peaking from behind a shelf was A- to make sure Adrien doesn't break her sister's heart. B- "who the hell is Lila cause I don't remember saving her?".

Their conversation mostly consisted of Lila flirting with Adrien, who seemed too innocent to understand. 

"I see someone's jealous", Mullo smirked as she flew out. 

"No shit. That's my boyfriend", I grumbled. 

"Woah! pump the hate breaks darling. I ain't the foe", Mullo chuckled as she turned to face the two, "Oh look, she's holding his hand".

"Thanks for the reminder", I spat as my eyes lingered on their conversation, which now drifted to the heroes of Paris. 

Adrien never had that book with him at home. I wonder how he got it.
