Santa, an 18-year-old high school student, is sweet, charming, and exceptionally talented in dance. His charisma captivates the girls at school, while the boys can only envy his looks and skills. Yet, despite all the attention, Santa remains indifferent as his heart is already devoted to someone else - phi Perth, his elder brother's best friend.
Perth, a 22-year-old recent graduate, arrives in the city X for an internship and temporarily stays at his best friend Pond's house. There, he reunites with Pond's younger brother, Santa, whom he last saw three years ago.
