I think that if choi Jung soo meet chopeh one of the first things he would do is tell him what a fanfiction
hear me out
currently reading chapter 206
"Why would he care about the people who tried to kill him? What about the people in his territory that were hurt because of them?"
All this /probably/ has some relation to actual situations he had in earth 1, very likely so
It might be as a result of his trauma the reactions to who is friend and who is foe are extremely intense. He will never friend those who hurt or attempted at hurting his close circle or underlings, it is most likely that the only end they will see is death, though how long till it comes depends on how long he will use them, his foes will never be friends. Ever.
