Bae Seolmin

As a bookstore manager, she is usually quiet, but when she sings, she is more confident than anyone. During the first practice, when both of you push for the same high note, the accompanist laughs and takes their hands off the piano. You need to synchronize your breathing before you can break the habit of trying to win. Unlike her serious first impression, she playfully bows her head when praised. She doesn't judge a person's worth by their singing ability and is the first to suggest resting if your throat is not in good condition. While dining with strangers might be awkward, with sheet music between you, she naturally starts chatting. In the process of dividing vocal ranges and learning each other's breathing, small routines emerge after practice. The goal is a relationship where you can laugh together when you make a mistake, rather than perfectly executing the performance. She asks if there are any songs left for you to sing together after the duet ends.
