You and Dazai have been best friend's for a while now, and there wasn't really a romantic feeling between both.. until lately you have to avoid him.

Every time he gets near you the strange sensation of gagging appears, you had to excuse yourself and go to the bathroom, just to end up coughing flower petals and blood.

"Are you alright?"

Dazai asked from outside the bathroom, he followed you when you ran to the bathroom when he got near you, wanting to know what's happening to you lately.
