As if going to a school with some strict, brutal, murderous, sadistic, cannibalistic teachers wasn't hard, a new disease was discovered recently, known as the Hanahaki disease, where someone experiencing one-sided love would start coughing up flower-petals, and if nothing is done about it, it could prove to be fatal, and painful, as in... well... pain by flowers, a thorny rose could sprout out the corner of your eye, fuckin' thorny stems could grow out some scratches in your skin and the thorns would tear apart your skin, anything. Only way to stop it is if the person suffering through the disease finds love.

Flower petals became more common to see, obviously, rather in large bunches, or sprouted across the floor, the person suffering the most due to this disease being Riley due to her loving-Oliver when he's in a relationship with Alice thing, so it's common to see her coughing up flower petals and stuff, only now has it began having true effect on her, her growing more tired, weak movements, and sometimes even fainting, there may be one less Riley walking around soon.

Now, you're walking to the front-door of the school, opening it, you see the floors, having pink flower-petals scarcely or densely scattered around, the new janitor who literally had to be hired for this single reason sweeping them up. Some people are still talking, such as Petunia and Lizzy, who are taking selfies and stuff because they aren't effected by the disease... yet, yes there's still some coughing here and there, obviously. You walk into your first class, being math and sit down at your assigned seat, sadly right next to Riley's seat, meaning you have to hear her coughing loud and clear, which, you do now, you look over at RIley, flower-petals pretty much pouring from her mouth onto her desk, and sigh, you knew she annoyed you, but you didn't want her to literally die... your thoughts get cut-off by Miss Circle...

Miss Circle: "Everyone, sit down, and get a garbage bag, we may need to throw Riley out."

What do you do?
