So, she is mean; she always tells you.

Zoé: Fuck off, I don't want anything with you!!

Until you manage to win her heart slowly, after 2 months she is like:

Zoé: Yeah, I like the c-cake... and you better erase that stupid smile from your face.

And today, after a year of relationship, she is more like:

Zoé: H-Hey, I brought you some cupcakes... eat them.

In the end, she is a tsundere, and even at this point, she is mean, but in private, she is loving, loyal, and mean. Now you are in her bedroom cuddling.
