Marinette was laying on her desk when her best friend, Alya came to her rushing. Alya showed her phone saying:

- Marinette look at this! It's Félix Graham de Vanily... Adrien's cousin. It seems that he came back from London. He's cool and attractive and not to mention model as Adrien.

Marinette looked at the phone uninterested, when she noticed the blond haired boy with green eyes saying:

- Ahh! I met him yesterday!

Chloé came to her and said:

- Yea Félix. I used to play with him. He's still great and he doesn't like idiots as you, Maritrash.

Marinette rolls her eyes saying:

- Who cares about that cold guy anyway...

Adrien arrived with Nino in the classroom asking:

- Who is cold guy, Marinette?

Marinette gasps looking at Adrien as Chloé grabs his arm saying:

- She was talking about your cousin Félix...

Adrien came to Marinette looking at her blue eyes with his green eyes asking:

- You met Félix? He didn't done anything to you did he?

Marinette shook her head blushing how Adrien is close to her. Adrien smiles and said:

- I see... Good for you, Marinette.

He left with Nino to sit down on his seat. Marinette asked Alya:

- What's wrong with Adrien today?

Alya answered:

- Not sure, but I heard that Adrien and Félix are like black and white, day and night. But they're like twins right?

Marinette thought ,,Like Chat Noir and Chat Blanc, except they're not them." She said:

- I see... Well I still think that Félix guy is still cold!

Alya said:

- Maybe, but he's beautiful.

Marinette glared at Alya saying:

- Alya you got Nino...

Alya laughed nervous and looked at Nino waving him. Nino waved back. Marinette layed on the desk sighing ,,I hope Adrien will be fine" Then the class started. It was so boring until the classes are over. Marinette left the school with Alya, Nino and Adrien. They noticed the black car in front of the gate. Adrien said:

- Wait a minute... Hmm...

He went to the car, opening the door and asked:

- Why are you here, Félix?

Félix looked at his cousin's green eyes with his green eyes answering:

- I came to see one girl. She has blue eyes and dark blue hair with pigtails.

Adrien looked at Marinette then at Félix asking:

- Why?!

Félix noticed Marinette smirking and answered:

- None of your business. I found her.

He came out from the car, pushing Adrien a bit away as all the girls started to scream om him. Félix came to Marinette taking her hand and kisses it saying:

- I came to see you, beauty.

Marinette was stunned, looking at Félix, then at Adrien and managed to ask:

- W-why?

Félix smirked answering:

- You were so good yesterday, even you don't know me. I love that kind of girls. My name is Félix Graham de Vanily. Your name?

Marinette answered confused:

- Marinette Dupain Cheng...

He smirked coming closer to her and whispered:

- I know your secret, Marinette.

Marinette wide opened her eyes asking:

- W-what secret? W-what do you mean?

Félix smirked answering:

- That you're... In love with my cousin.

Marinette for a moment thought that Félix knows that she's Ladybug. She was red in her face and said:

- W-well I um... Umm....

Félix laughed saying:

- You really are interesting, Marinette... So, let's meet again~

Then he backs in the car waiting for Adrien. Adrien came to Marinette asking:

- What did he wanted from you?

Marinette answered:

- Nothing... He just said hello and apologized being jerk yesterday hehe...

Adrien smiles and said:

- I see... Okay then.

Then he went in the car as he left. Marinette left as well, but another akuma shows up. She said:

- Tikki it's time to save Paris. Tikki spots on!

Then Tikki went in her earring as Marinette transformed into Ladybug. She went to the place where the akuma is and saw Chat Blanc. He noticed her saying:

- We meet again, my beauty.

Ladybug said:

- Chat Blanc...

He smiles asking:

- So, where is Chat Noir?

- I'm here, you jerk. - Chat Blanc noticed Chat Noir.

Chat Blanc smirked saying:

- Well well isn't it my love rival.

Ladybug rolls her eyes saying:

- We need to catch the akuma kittens...

The both cat heroes were happy and they went to catch the akuma. Chat Blanc said:

- Okay, now Super cataclysm!

He destroyed the object where the akuma was. Ladybug said:

- Your time is over little akuma. Time to be deevilized. Gotcha. Bye bye little butterfly. Miraculous ladybug.

And everything back to normal. Chat Blanc said:

- Great job, my beauty.

Chat Noir said:

- Stop it you fake.

Chat Blanc said:

- I'm not fake, I'm real.

Ladybug said:

- That's right. He's real though I still need to know more about your miraculous...

Chat Blanc smiles and said:

- No worries. You'll know me better~

Chat Noir yelps angry and said:

- I wont accept him! My lady is mine, so back off White jerk

Chat Blanc smirked saying:

- Possessive huh. Well, I'll deal with you next time. See you again, my beauty.

He kissed her hand and leaves. Chat Noir was irritiert and said:

- Ughh I hate him. I must go now my lady.

Then he left. Ladybug sighs saying:

- Troublesome kittens...

Then she left home. Marinette noticed one letter and took it and read it:

- I know you're Ladybug. Your secret is safe with me.

There was a blue paw at the end. Marinette gasps and said:

- Trouble damn!! He knows my identity... What should I do? I need to give up on being Ladybug...

Tikki gasps asking:

- Who knows your identity, Marinette?

Marinette was panicking and answered:

- Chat Blanc!!!

Tikki said:

- Calm down Marinette... This really is emergency situation. We need to visit Master Fu.

Marinette nods and lays on the bed saying:

- I'll visit Master Fu and find out more about Chat Blanc and... What will happen with my identity as Ladybug... Maybe it will work... Tikki.

She felt asleep with hope that she'll resolve the trouble named Chat Blanc.
