1. The ML told Mesan about his plan to destroy the exorcisms organization that's why Mesan believe him immediately and this is also the reason why he wanted to recruit MC to be on his team (a little intermezzo abt the organization, it's called 나례청 romanization: naryecheong, it's actually also a culture reference from ceremony in korea, i think the root of this specific ceremony is from china, which basically a ceremony especially on new year's eve on lunar calendar when you wear mask and chanting a spell to drift away evil spirit from year before so that they can go with a "new spirit" for next year, most of the time they'll wear mask and bring some sort of tools, if you watch exorcism in korean tv media like movie "exhume", you'll probably understand it a lil bit. They'll held this narye/나례 ceremony for government office, new home, etc. So yeah that'd be the reason why ML mostly wear mask when he's on duty) 2. He's gonna make the rest of the team forgot about MC's identity, basically like erased their minds. Some of them gonna be in a critical condition cause MC basically hurt them all with the intention of killing LOL ╮(￣▽￣)╭ 3. The "teacher" of the MC is actually still blood related with ML 4. The novel itself, i can say it's pretty graphic and have a looooot of references to the Korean's folk, spiritual being, beliefs, culture and etc. Basically the next chapter, MC gonna used his own bone and blood and make it like some sort weapon (bow and arrow) 5. Oh and they're gonna clear up the misunderstanding part because Mesan would told MC about ML true intentions with the organization and that he actually not the one that kidnapped him 6. Before ML enter that exorcisms organizations (naryecheong) they have a contract by blood, so you can't hurt the fellow exorcist or use spiritual spells to them, that's why ML need MC to team up with him cause they have common enemies and he can't take down the whole organization by himself. Also in the next chapters, ML gonna coughing blood cause he already broke the contract when he erase the memories of the other exorcist from the organization. When you break the contract, you'll feel the pains as if like you're leading to death.
Just a little bit of spoiler but basically:
