I have read the fandom wiki on how to trigger the event, but i cant get minami to appear in the living room from 20:00 to 22:00
Did u use random girl schedule?
I use random girl schedule, the living room was however empty when I entered it.
Try using a fixed girl schedule.
Nope, it still didnt work whether she is in or not in the living room during 20:00-22:00. The scene just didnt trigger :(
