If you had the chance to turn back time and fix just one thing, what would you choose? Forty-four-year-old office worker Win leads a life devoid of purpose after losing his close friend Nut along with the dream they'd shared. One day, fate takes him back in time to the age of seventeen. This time, Win's determined to successfully fulfil the dream in Nut's diary by molding the band the two had started and leading everyone onto the Star of Band competition stage. The more Win endeavours to alter the past, however, the more the clock ticks towards Nut's end, and the more afraid he becomes that it will come time to lose Nut once more. This time, will he dare speak the feelings his kept in his heart these past twenty years?
