developer promised no long ago that the time of rescuing a girl from a villan will be shorter. Since then,it is the opposite, winning affection for girls (common or event) is very scarce. Is it a bug, or developer did't had enough time to implement the promises.Yes , it is very frustrating using all your energy during an event to win a girl(with a lower compensation in money, compared with what you can win at your current level) and at the end having to wait another year to get the girl. Using real money to buy cobans(energy) will become the only chance, at this low rate of obtaining affection. I will try to stay away from event girls,if the event is just 4 days long. I did won 2 girls in a longer event !
good luck to all
