since they changed affection this game has become a grind to catch up game. before 2.0 you literally could upgrade every girl to max as soon as you got them and the limiting factor where the levels as XP items were low value. with 2.0 I think there was a single moment were I had everything max'd, but since they throw out 5 star girls frequently it is impossible as I am barely able to keep up with all new and revival events - I basically stack up affection items inbetween events and most of it will be gone with the next event so I can upgrade like one girl from 3-4 or 4-5
