Hiiii, I found this story from the Instagram feed of Sahiba KT and I guess this is your work here too, I also know you from Wattpad! AND I LOVE ALL YOUR WORKS ON WATTPAD!!! I know your writing styles, so I am so looking forward to reading this story, first I just made the account so I'll go and save the story in my library first!
