I think that mc and ml knew eachother in the "other world" and I think that they both transferred into a novel after dying in some accident.. Bc you see, in chap 6 mc has a dream with memories from his previous life and he meets a sunbae there that has the same earnings as ml, which lead me into thinking that they are the same person.
Also after mc tells ml that he has a little brother, ml mentions. that he was pretty sure mc has a younger sister, which is true but in the "other world". I think ml lost most of his memories but remembered a few things like for example, mcs face. I think that's why ml let mc drag him around when they first met and paid for mcs hospital bills.
These are just my speculations so if anyone has read the novel pls spoil me!
