I read somewhere that ML needed to kill MC 7 times in alternate universe before get in the current timeline. I'm not really sure. Also, the ML will disappear because it's just borrowed time where he doesn't age or get sick. MC will also sacrifice to get him back so they'll be both immortal. Unfortunately, they can't have a baby :((((hopefully the ending is different here.
