For Yoo Jae-Min, debuting as an idol is everything, but his skills are outshined in particular by Jung Woo-Hyung. The other boy's laid-back attitude, especially toward their fans, irks Jae-Min, but their dynamic shifts when they become roommates and Woo-Hyung starts noticing cute sides to Jae-Min that he hadn't before. The fans notice this change and Jae-Min focuses all his attention on them and their love, which bothers Woo-Hyung. Will their group, 4ever, hit it big, or will Woo-Hyung and Jae-Min's tumultuous relationship lead to its downfall?
