The flowers bloom with emotion, and life is lost at full bloom.
In this world, love takes your life.
Emotions make the flowers grow, And the flowers scatter your life.
The name of that disease is—Hanasaki-byo.
A body in full bloom quietly ceases to breathe, leaving behind only a single flower. Therefore, a patient must never fall in love.
A doctor's words to a certain Hanasaki-byo patient
"It's Hanasaki-byo. I'm sure you're shocked, but please stay calm first. It isn't a disease that will take your life today or tomorrow. However, from now on, please do not fall in love with anyone. That is the only way for you to live a long life. These are the precautions we give to all Hanasaki-byo patients. It summarizes the rules you must follow in your daily life. Please read through everything and adhere to them as much as possible. Also, if you notice any changes in your condition, contact this hospital immediately. I will prescribe some medicine. It will help ease the pain and temporarily suppress the progression of the bloom. However, it is not a cure for the disease itself. ...Take care."
