Troye has a tumor. A life altering, pain sparking, malignant tumor. He's uncurable. He can't be fixed, he can't be helped to a large extent. One night, after overhearing a conversation between his brother and sister about him that was definitely not meant for his ears, he becomes determined to see them. He needs to see all fifteen of his best friends, of the people who mean oh so much to him. He needs to let them know their importance in his life and so he makes a list. He makes a list of the fifteen people he needs to see before he dies. In Tyler Oakley, he might find more than just a best friend.
