at the start of Season 2 of Love Live! School Idol Project the first years are running around the place trying to find Honaka to tell here there is a second Love Live competition noting that the first one was so popular that organizers decided to hold a second one.
But it was my impression Love Live was held before Season 1 since Hanayo and Nico already knew about it when μ's formed. so hasn't Love Live occurred in previous years?
