To me its a backwards system when it costs so much to raise affection levels. It smarter as it is now for players just to play epic pachinko. They can sell back what they don't need and also get the items they need for battle, plus not have to pay kobans for boosters. You want to raise every girls to max affection to get more money. You will only have a few girls that you need to raise levels on. I would have held on to the gifts I sold had I known the system was going to change that drastically.
