Voyage to a letter (Troyler AU)

Marcus Butler is approached by an old man named Tyler Oakley on the day of his graduation. Why this old man wishes to travel across the US to California is a mystery, and why he intends to fill out a bucket list is an even bigger one. But the man offers to pay for the journey Marcus has always wanted to take, so why not?

What could really go wrong?

This will be a Troyler AU even if it doesn't necessarily begin that way...and it'll be cute....I hope :3
