I usually get this one in the morning at 9:00 on the days Sasha doesn't go straight to work after her shower and Minami doesn't go straight to university.Do you know how trigger the minami and sasha event? I see in the wiki but the event doesn't start, i don't know if you can missing the event if you have manami more that 80 love point.
