One of the former NPCs starts by saying "Everything that you heard about High Humans is true" to the other people in Hinomoto but never explains that Shin is one and only that Shin is stronger than Shnee, like it is cool that you are not revealing his identity as he wishes but why did you bring up High Humans in the first place then?
even though he is literally carrying around the heart of the demon lord, and before it stated her reasons as being told by God that his death would allow a redo I assumed it would be because she would be the one feeling betrayed
His informant friend wanted to confirm whether or not the stories about the MCs past were real so he brought him to a slave market which is an establishment he would hate due to his past.
He is a quick learner but she is going to be disappointed soon because only got so far recently after another woman gave him advice (actual advice with words) and it will stagnate if he doesn't start learning for himself
seriously after making one Young Master rape another Young Master neither is mentioned again though one young master's father still has a grudge against him brought up that is it.
Based on what some others have said and what I know he should just kill Ma Yixuan, she hates him for no reason and instead of saying something to him to get him to give up she has purposefully gotten his hopes up before knowing he liked her and at other times tried to have her boyfriend and his goons beat him badly because she is disgusted by him. At the point I'm at I have to say why hasn't she knowingly attacked the MC yet, she thinks he is strong but doesn't know he is a cultivator so she should try to attack him seeing as she is already on the same realm as him (technically until just recently she was higher). Though I have to say part of their relationships reminds me of the first part of Pure Love x Insult Complex where the older sister is Yukino (to an extreme), the younger sister is mana and the main character is Yoshinobu. By that I mean he is disillusioned by his first love and while he holds a fondness for her has gotten over her and the younger sister is actually salvageable and they were actually both mistreated by the older sister.
He also essentially creates his own private army which is pretty boss
