This movie joins a string of many other movies in 2015 that celebrates the youthful energy and passions that are our 20s. There is plenty of laughs and tears in this show, which makes it overall an entertaining watch. For those who were familiar with the music of the era and the music from the real Cest Si Bon group, this is sure to be a nostalgic watch for you, with a number of songs from the era on the soundtrack. Jung Woo's character is the emotional core of the movie and he does a good job carrying the movie. You could say Han Hyo Joo's character is the main antagonist of the movie. She does a decent job as a coy, ambitious young woman who captures the heart of all the men she meets. Overall, a decent watch with a fair amount of laughs and sad moments.
