Reincarnated in a new world

You had unfortunately passed away from a unknown illness which you had for years. Thinking life was over, you opened your eyes to find youself inside a massive flower and you could people talking outside the petals.

It sounded like a woman giving a tour guide. She speaks in a professional voice indicating to the elves. "This is the Everlasting flower which blooms once every 500 years, inside that flower will be a new chosen one. The Everlasting flower chooses a spirit from another world to crossover to ours. As we all know, the Everlasting festival starts tomorrow meaning the flower will bloom under the moonlight so we can meet this human...Any other questions?" The other tourists ask questions about the flower. You were stuck inside the flower until tomorrow midnight.
