Marinette POV

I was in class staring at Adrien when I was brought back to reality by my  teacher Mrs.Bustier announcing something.

Mrs.Bustier: ok class i have great news

Everyone was waiting for her to finish what she had to say.

Mrs.Bustier: we're going to China for 4 months a week after we get there we are invited to the coronation of the crowned princess of China

Everyone then erupted in cheers and excitement. Except me because no one knows that I'm the crowned princess of China. So they'll be going to my coronation. I'm excited to go home but a little nervous what everyone would think.

Mrs.Bustier: we told all your parents and they agreed to let you go and Marinette your parents are outside and would like to talk to you and Alya

Marinette: Ok

Then we got up went outside I saw my parents. They were smiling at me and I looked at them. Then they looked at me with the you can tell her look. Then we stopped in front of my parents and I took a deep breath. And looked at Alya.

Marinette: ok you know we're going to China and to the coronation of the crowned princess of China

Alya: yeah

Marinette: well I'm the crowned princess of China

Alya: you serious

Marinette: yes and you can't tell anyone until they find out in the coronation

Alya: OMG GURL THAT'S AWESOME!!!!!!

Marinette: I know

Tom: we decided we're going to let you have some fun you can ride in limos and wear your dresses

Sabine: and don't forget to rub it in Chloe face and don't hold back

Alya: I love your Mom

Marinette: she's the best

Tom: Marinette we're leaving today and you all are leaving  tomorrow and you have first class seats in the plane and we  got the whole first class  so you can invite  anyone

Marinette: thx mom and dad I'll see you tomorrow I'll get to come to the castle right

Sabine: not tomorrow wait a day or two

Marinette: got it

Then they left and we went back in. I whispered everything to Mrs. Bustier. She was shocked but then nodded and I sat in my seat. After school me and Alya were talking when Adrien and Nino came  over. I started blushing and smiling shyly.  If you didn't know I'm in love with Adrien. But to lovestruck to tell him.

Adrien: hey girls

Nino: hey dudettes

Alya: hey boys

Marinette: h-hey

Adrien: you guys excited about going to China

Marinette: OMG YES VERY EXCITED CAN'T WAIT TO GO TO MY HOME COUNTRY !!!!!

Adrien: your from China

Marinette: yes

Adrien: cool

I then blushed and giggled. We talked about it and then went home .I took Alya home to pack and then we brung all her stuff to my house. I then started packing .
