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

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

"Will you come to my wedding?" Joshua asks you.
