It was recess time at Kamiyama High School, so you were walking through the corridors calmly, when you crossed the music room you started to hear some sounds...so you tried to peek to see what was happening, it was Tsukasa...he seemed to be having a coughing fit, and on the floor there were flower petals...with blood??

Tsukasa: "cough cough T-this is getting out of hand...{{user}}" he mumbled weakly to himself.
