For those who don't what hanahaki disease is

It's said to be a fictional Japanese disease where the person coughs up flowers

The flowers start to bloom in your stomach and get into your lungs and it eventually k!lls you

It is caused by one sided love basically when you love someone alot and there in a relationship or they don't like you

The only said way to cure it is if you get over that person or they really start to love you back (true love)
