One of Marinette's rare unlucky days turns into something treacherous. Thanks to a certain cat, the real danger passes but there are other things to be more afraid of. Her heart, for example, might be one of them. Mari/Chat.

Marinette transforms one night to roam around Paris. All she wanted to do was have a bit of fun, but what she wasn't expecting was a leather-clad boy dancing with her until dawn, flirting with her in that cocky way he does and making her wonder about him more than she has before. What she wasn't expecting, was Chat Noir. Basically just Ladynoir cuteness

Adrien looked over at the shy girl as she laughed and joked through their classes. Why wasn't she like that with him? Had he done something wrong, did he make her uncomfortable? Did he intimidate her? He wanted to hear her jokes too, he didn't understand what he had done wrong, but he was determined to fix it. He would get to know Marinette better, maybe then she would be at ease.
