Im just trying to think of how to make you cross paths, but all I can think of is you all are in the same place at the same time somehow (like maybe you all cross paths while going somewhere by coincidence) and you all see <The Gamer> floating above the names floating above your heads (like what the MC's name reads in the Manwha)

Then NPC interaction happens and you may all make plans to figure out more about this ability. 

That's one thing I can think of.
