Okay so bitch tried to kill mc. At that time the remaining points of ml's added up and became 100. Thus system told mc bc the points are sufficient for ml to fall for mc, and his mission got completed, mc can choose to leave the world or stay (till he wants). Then mc asked the system, what might happen if he stayed in the world, system told him it depends (means it depends on the will of mc, if he could live or die) so mc looked at his crying/worried friends and ml, he decided to choose to live there. Afterwards it showed what happened to the bitch.

Mc didn't die, he just fell in coma. Thus the remaining panels where, what happened to bitch shows is the time before he wakes up from coma.
Oh good, I thought he died. Thanks for explaining it
Uhhh, my stupid brain didn’t process what happened in the last chapter. Can someone explain it? (づ￣ ³￣)づ
