So this summery will be major spoilers ofc just so you know before hand. So basically wang yi (pink hair mc) was once a system(like what s0 the green cat is) named Y. Qin xian (the black/purple hair who plays as thr hero in every world) was once a host(someone who has a contract with a system to travel around and complete stories) who was under Y and he went and played villain roles. White (the white haired dude with multi colored eyes) is a lesser system than what Y was and was a companion and friend of Y. He broke himself up into many pieces to collect vitality so that he could gain power and eventually destroy the main system along with what Y was doing. So Qin asked Y if he wanted to become a human at some point but Y determined it was impossible but in chapter 171 we get to see that Qin managed to achieve this by sacrificing his own body to offer Y a human body. Y gives him a potion of reincarnation so that Qin doesn’t truly die. Y looses all his memories when he becomes a human and turns into Wang Yi who then losses his friend and creates a contract with S0. S0 is actually behind the scenes and helps take Wang Yi to worlds in which Qin Xian’s fragments have reincarnated so that they can reunite. It just takes time for them both to slowly regain their memories and for Qin to start combining the fragments of himself back together. Sorry if this was confusing I started ranting
I have been reading this since a long time ago but no matter how much gets revealed I’m still so confused on what’s happening sometimes ┗( T﹏T )┛
