preview in the trailer!!!! select 予告編

edit: she sounds like she is singing it without much emotion but she sounds mature and kinda different...but the song is nice...kinda different from her usual ballad i feel...i can get the summer feel in there coz of the slight rise in the last note....and the end melody feels moving like walking proud for me...
i can see that Ayu is gonna perform this with emotion...i like the song! i like the way it ends off with that kinda hopeful tune
