song of my home. (Tom Holland x reader)

Y/N moved to London when she was only three years old, her and her mom were going to live with her aunt. (Dad's sister that's why Y/Ns, not British) when they got there, she met her cousin's best friend, Tom, and from that day, they all were inseparable until Y/N turned 12 she and her mom moved to CA. What will happen when Y/N moves back to London 5 years later? Will she and Tom still be best friends, or will they have each other replaced by then? Guess you're going to have to read to find out.
