The great war

We all know that shelly met mahon (Jay's uncle) when she was young, and that mahon talked to shelly about introducing his nephew to her since they are the same age.
But what if mahon actually introduced them to each other? What if they actually became friends?
What if they only fell apart because of mahon's death? Since they lived so far away from each other and they both were grieving. Both slowly forgetting each other.

What would happen if one day, shelly came across a picture of her,Mark,mahon, and jay. And she doesn't remember the little boy in the picture. Is that why she came to Korea? Will she meet that boy again? Idk
