That don't works. You can get only 1 FG per girl maxed affection. Maxed affection dupe gives nothing. I tried it. It's better to keep the maxed one and sell the other.For the ones that have 99% affection I use a Nazuna Cake to get them to 100% and get a flower gem. I then sell it for bond crystals leaving me with the 0% affection one. I dont really use event girls anyway (except for some like adenium rainbow rose and lilly of the valley?) so id rather get stuck with the 0% affection ones to then get another flower gem if I decide on maxing their affection
Meh... delayed Mobile version is... bad news. I need my free 6* before I buy one with R medals.
