MC has a villain system, he wants points to get prop to go back in time and prevent his classmates from dying in a bus accident. ML can read people’s minds so he knows MC is forced into role of a villain.
ML seems to be a past system host that was so OP he became legendary, used his points to get ability to “see through people’s hearts”, but when he returned to his world something happened (went crazy?) and his soul shattered into pieces. Also, his own system appeared to have the same face as the MC (and later ML wonders if he knew MC from before) — maybe the MC was originally the ML's system and became human?
The interesting part is that both MC and ML are a bit (very) crazy. ML wants to trap the MC for himself (more possessiveness than pure love) and MC is a psychopath (killed animals as kid, imitates emotions, enjoys seeing people’s faces twisted in pain/suffering, has to make an effort to be a good person). First world ends with MC using chloroform on ML so he can leave the mission world and ML says he won’t let him escape.
The ML, about the MC, “If a bad person pretended to be good their whole life, are they still considered a bad person?” Gosh, love the dynamic.
