Kim Hayeon was just covering for a friend at their day job when she unexpectedly ends up inside cellist Ji Sehun’s private waiting room. Despite his immense musical talent, Sehun is aloof and cold-hearted, and doesn’t take kindly to Hayeon’s intrusion. Though he accuses her of attempted theft, he cannot get her out of his mind, and attempts to court her. But while Hayeon may be timid, she is not easily won over. If this cellist isn’t careful, he may end up being the one getting played.
