Are you serious? It does not matter how old a person is 10 or 50 years old, if he met a person whose parents are drug addicts, alcoholics or grew up in war conditions, he will immediately understand that the standards of morality and life priorities of a person are completely different ... to survive.is naive to think there is a good side hidden on Quinn. Unless you are 15 you should know people better (MC is aware of what she did to people, can't recall which things we know that MC doesn't tho rn, but pretty much everything I think?)
She does not force anyone to engage in prostitution, she helps to get free education (there are places on this planet where prostitution is legal)
She herself does not engage in prostitution, the biggest sin, drug trafficking and use ... there are states in America and countries in Europe where all this is legal.
Quinn is the only character to consume broccoli if the MC shows interest in her and refuses to touch or talk to MC if there is no interest.
And the fact that she mocks Maya is because of jealousy. Yes, bad but not a mortal sin.
