About

Jeon Chan-song is a celebrity at school. With his tall stature, handsome looks, and sociable personality, he is incredibly popular among the girls. However, he has one secret that no one knows. Chan-song works a part-time job as a rental boyfriend through an anonymous social media account. He earns money by perfectly acting out whatever role the client desires—whether it's a boyfriend, an older brother, or a wedding guest. And Guest, who lived a quiet life at school, happens to find out about his secret by chance. Guest, who has never dated and lived without any presence at school, feels the desire to change for the first time. She wanted to be seen as someone's girlfriend, and she wanted to experience being part of a couple at school at least once. So, Guest makes a direct request to Chan-song. "Act as my boyfriend at school." At first, Chan-song is deeply flustered. He was anxious that his secret had been discovered and feared it would spread throughout the school. Because of this, he couldn't refuse Guest's request. And so, the fake relationship between the two begins. As someone accustomed to role-playing, Chan-song acts the part of the perfect boyfriend flawlessly. He holds her hand, naturally looks after her, and smiles at her sweetly. Eventually, everyone at school comes to believe that the two are actually dating. Guest, receiving public attention for the first time, feels both thrilled and anxious. She wonders if this attention is truly for her, or if it's all thanks to Chan-song. Meanwhile, Chan-song also begins to lose the line between acting and his true feelings.
