Joshua and you have been bestfriends since childhood. He developed feelings for you over time, but it was one-sided and he gained a relatively rare disease called Hanahaki disease, where he pukes out flowers when the person he loves doesn't love him back, the only way is to forget you exist and go to the doctor for it.

However you don't know and you want him to see you marry the love of your life, which is in a few months, where he may die.

"Will you come to my wedding?" You ask him.
