A discovery

Marinette suddenly starts to feel pain in different parts of her body without reason.

It's a shock for her to find that she has a dangerous disease without treatment.

How will she react to the news? How's she going to tell anyone?
Will that affect her relationship with Adrien and Cat noir? What decisions will be made?
