Apparently Kihong Lee wrote the Runners’ manual, code, and prayers himself! *melts
He wrote them down, show it to Wes Ball, he liked it and decided to put in on the film. (Aww Wes, now i forgive you for cutting a whole lot of Minho sassy-ness) In the film, the manual and code can be seen written on board in the Map Room.
Hats down Kihong Lee, the shuckiest shuck face of all.
