Hello, Kiki_Kk11. I'm very sorry, but I'm not really open to this idea. It's basically an unwritten rule of Wattpad that you shouldn't promote your story on someone else's story (or vice versa).
If you're looking to increase publicity, I would suggest adding as many tags as possible. (I looked at your story, and the limit is 25 tags; you currently have 15.)
As well as this, you could "write ahead", as I call it. This means that your story is a few chapters ahead of where you've updated (eg. You have just uploaded chapter 15, but you have already written chapters 16, 17 and 18). It also relieves a bit of pressure.
For me, I had been writing my story for a few months before I got my Wattpad account, so I had fifteen-or-so chapters of backlog. I uploaded only up to Chapter Twelve, so I still had chapters 13, 14 and 15 as drafts; I just kept going from there.
Sorry this is so long and, again, sorry I can't agree to your offer. I don't think it's fair that I would be doing your publicity work for you. Have a nice day :)
