In zeikun route, day 80 it wont allow me to continue and it says "required more affection points to unlock after story" and "end of chapter 4" okay i'm confused how do i get affection points? or do i need to finish all endings?
Those are all the "ping" sounds during choice making. In other routes it's crucial, because those points decide which ending you get. In Zeikun's route it's one choice moment that decides.
