The little face in my memories, like the smile of an efflorescent flower.[I changed your sentence a bit, I hope that it's what you actually meant to say.]

Long, long ago there was a boy who loved you so long for a long time, but, with the steps of wind, all things have gone.

But with the steps of wind all things have gone. I added this onto the end of the previous sentence because it sounds more natural. I also inserted the appropriate commas.

How long I have to waited to see you again, but at the end of the fairy tale you eventually said "bye-bye." [I added the next sentence onto the end of this one. Arguably, I could have inserted some commas, but I chose not to this time because it isn't too important. Always remember to put periods inside of quotation marks. It should look like this: "I was happy." It shouldn't look like this: "I was happy". Let me know if you want me to explain that any further.]

But in the end of fairy tale you eventually said "bye-bye".
