When was the last time some snotty ass conceited side character who disses and bullies the MC ever get a second chance? Luo Li my man, I'm looking at you! You make me proud! You bring hope to snotty brats!
As we get to later chapters, I realize that Zuo Mo is good at delegating. Not a perfect leader from the get go, but he is so resilient that he doesn't mind learning from others, namely, his subordinates. He has trust. Especially in the later chapters. MCs tend to be quite literally, gods. They can do anything and everything. Zuo Mo can't. And he knows it, embraces it and uses it to great advantage. Truly refreshing!
I like how he literally creates his own country and tries to get it to be as modern as present day Japan. Which is ridiculous in the context of the novel as they were in medieval times.
Let some other concubine become favored so that they are public enemy no 1. Never thought about it that way!
He does eventually warm up to our female lead and becomes rather nice/protective but it does take a while. Like beyond 200 chapters kind of slow. I don't want to spoil for anyone
Then they promptly get wiped out. Whew.
I think he was being a ruthless miser because he knows that these people would not let him go. He's done too much and he actually has some pretty admirable ambitions which fuels his actions. He's a miser because he comes from a relatively impoverished village. Everything he gets, he has a mind to share everything he gets with his village. Yes, he's a glutton, but that's his drive to become stronger since in this novel literally everything he eats powers him up. He has a good personality in that he is one to repay kindness where its due, ie, Williow Diety, Stone Village, Great Vine Spirit, the elders at Heavenly. So I think his personality is pretty constant.
