Sharp(2003)

Sharp is a Korean series following 15-year-old Lee Ok Rim, a frank and confident girl caught between two very different boys. At home, she navigates life as the middle child between an accomplished older sister and a twin younger brother. Ok Rim dates Yoo Ah In, a talented high school painter who's mature and controlling, winning art contests through intelligence and persistence. But her feelings complicate when Jangwook, her longtime best friend and next-door neighbor, enters the picture. Jangwook is shy yet cool, warm and popular, knowing all her secrets. As Ok Rim struggles to understand her own heart, the two boys compete for her affections in this coming-of-age story about teenage romance, friendship, and self-discovery.
