worst for me - i used "Gacha" where i got affection increase. That prompted me to spend more time to get those 800 points, as every 20th click would give me not 1.1 affection, but 5.5 affection. so, that is 9000 kobans for Gacha, 2000 kobans from event, and 250 + 800 affection points from event just vanished
