Yeonjun, Soobin, Beomgyu, Taehyun and Hueningkai were princes on their planet but one day they ended up on earth. They had to experience the cruelty of this world. Yeonjun, as the oldest, was able to find work in a small restaurant as a cook and a waiter at the same time. Soobin was a cleaner in that very restaurant and all the younger ones helped with unloading food, but did not officially work due to their young age.
