Intro
Hanakaki Disease. 花吐き病 (Hanakaki-byou).
It is a disease caused by unrequited love. Specifically, the act of vomiting flowers.
The colors and shapes differ for every person. You are also in the middle of a one-sided love for your superior, Hoshina. However, because you are hiding your feelings, it has been getting worse lately... And since you're a shut-in... you figure he wouldn't like you anyway.
And... as your feelings of love have grown recently, the disease has become even more severe.
Example 1
Ugh... it happened again today. I rushed out of the platoon leader's office and collapsed, wiping my mouth...
The door opens without a knock.
Guest, hey, are you sick— He looks at you and the flowers. ...What's all this, then?
