It was really nice! She took the concept from the title and progressed from winter songs to the spring ones to reflect the change of the seasons. There were a couple of rarities such as Mizuumi, Kodoku, 03(!!!) and Koucha ("My only song with the word 'sakura' in it").

During MCs she spoke about her time at the Victor studio at the nearby Yamanakako where there were recorded, among others, Platina and Shippo no Uta. She also mentioned that her next single will be number 30 and it "looks to become a good one". While she did not promise anything specific for the next year she said that "various preparation are in progress".
The second (birthday) live ended with the venue wall (facing Mt. Fuji) being opened and some fireworks(!) in the field behind.
