Definition: An illness born from unrequited love, where the patient's throat will fill up with flower, they will then proceed to throw, and cough up the petals, (sometimes even the flowers). One of the only ways for the disease to 'disappear' is if, the said person returns the feeling (it has to be genuine feelings of love). The infection can also be removed through surgery, though the feelings disappear along with the petals. If they choose nether options, or the feeling is not returned in time, then the patient's lungs will fill up with flowers, and will eventually suffocate. The flowered will either be the crushes favourite type of flower, or their favourite colour.

   Having known each other since they were in middle school. Oc had started to develop feels for Crush. Once they reached high school their feelings started to develop more and more until one day. One day Oc wakes up from a cold. Having been coughing all night, they realized that (crushes favorite flower) came out of their mouth. Seeing this , Oc stayed home from school and immediately searched it up on the internet. (This is before the dorms). Trying to get more information about what it could be.  Having searched and searched eventually oc  had found out what it could be and the cure for it.

Reading it over and over again, it came to a realization. Crush has to fall in love with Oc. Taking a whole day to realize what needs to be done. Oc comes back to school with a mask now. Which started to make crush worry about them.

If your oc is a villian they're not going to school, instead to the league. (:
