I've seen your posts and the word that I came up with was "full dedication".
I don't think this is the perfect word to put it but I hope calling it this ways would make it sound less cheaper.
I have a question too and it is "Do you think this story is a happy ending or sad ending?"
Although the flower bloomed the like shape of the fan, they can never meet again because the fan broke into shreds. This part kind of made wonder whether this story ended happily. Please give me an opinion if you can.
