Actor Lee Jun-ki ropes two longtime friends into investing in the Seoul guesthouse he runs on the side, where their old crush from school comes to stay.
Lee Jun Gi is an unpopular actor who runs the Waikiki guesthouse. However, business is bad, and the guesthouse is facing bankruptcy. In order to revive the guesthouse, Lee Jun Gi asks his friends Cha U Sik and Kook Gi Bong to invest their savings in it.
Cha U Sik is a picky person who dreams of becoming a singer. Kook Gi Bong used to be a promising baseball player, but is now stuck playing in the minor leagues. After Lee Jun Gi's request, they all put their money into Waikiki Guesthouse and start living there together.
