Cha- sik wants to prove to Jin-mok that he's the son of the Wise Man by winning the piano competition. He asks Yoo-seul to accompany him to the piano competition, and Yoo-seul teaches Cha-sik to play the piano. Meanwhile, Jin-mok's father tells him that he shouldn't be fooled by his talent and focus only on the piano, but should also prepare for the SATs. Conflicted, Jin-mok begins to worry about Cha-sik, who is far less talented than him, and Yoo-seul, who is in a much worse situation, as they practice for the competition. (thetvdb.com)
