Chat Blanc read the entire diary.

Pages and pages of marinette talking.

About him.

How much she loved adrien.

How much she needed cat noir.

Chat blanc could feel them inside of him.

Trying to convince him to come back.

Because the only other thing in the diary was mari talking about chloe.

Chloe being a bitch to her.

Chat blanc didn't want to understand.

But..

Now he did.

He saw how much marinette cared for him.

But then he realized.

She cared for adrien and cat noir.

Not chat blanc.

The side of him that was hurting.

She didn't give a damn about that.

He leapt of her balcony just as she woke up.
