Hikaru was sitting next to Kaoru staring intently his eyes on his crush Sheila just admiring them from a far, grabbing his throat holding it as he felt a pressure build up, saliva gathering running to the bathroom slamming open the stall door kneeling in front of the toilet

Feeling something caught in his throat like he was choking, leaning over the bowl coughing out his lungs trying to get everything out, horrified when he saw blood and....Blue rose petals?...he had the Hanahaki disease
