This is a soulmate Au. It is MyLock, but it is not Holmescest. Mycroft and Sherlock are soulmates but they are not brothers. I know, I know, kill me now. Anyway, the theme: "What happens when you meet your soulmate in your mid-teens only to find out that he is just a toddler." Lest assured, there will be no creepy child sex or anything. After all, our two guys are not child molesters. Cover is art by WuLiao-Yuzi : https://www.deviantart.com/wuliao-yuzi None of the pictures are mine.
