the Teachers Rights Protection Agency was created by Gangseok and Hwajin. Hwajin was Gangseok's daughter's fiance, they both lost her 2 years ago, by one of her students beating her to death, which is why they created the TRPA.

Right now

Hwajin Na was sitting at his desk smoking, Hanrim Im was sitting at her desk checking Gu Sera's reports as Gu Sera waited nervously, Hyun Daniel was reviewing reports on their website while Gangseok was in his own office alone.
