Hanahaki Disease AU

If anyone doesnt know,Hanahaki Disease is a fictional illness,when a person experiences One-Sided Love,then they start coughing up Flowers or Flower Petals (for this one we're using their fav flowers). This is actually Deadly,since the flowers can clog your lungs and you die from lack of Air. What do you do when one day,you're coughing up Petals?!

Out of my OCs,Alois has the worst Case of Hanahaki. Followed by Yukino,then Gamon,and the last one is Jeanne. The others are clean.
