Sanzia's Song
준서 (Jun-seo) is a smart, popular, and good-looking guy at Daechi High School. He's known for being cold, rich, and introverted. After his mother left when he was a child, he became withdrawn and non-talkative. Now, he lives with his father, the Chairman of Seoul.
On the other side, there's 시우 (Si-woo), a smart and charming boy who loves playing musical instruments like the piano, flute, and his favorite, the kalimba. He transferred to Daechi High School because his previous school didn't support music.
