I had to finish 2 assignments for University due in for today, so I didn't get the event SR's because I haven't play either version since Saturday, also, I've got 68 love gems on my japanese version, but no space to do a 10+1, is it worth buying more space (with loveca)? or should I just keep leveling my idols up and then feeding them to the next one to level up until I have space.
