Jeong Sewoon's song ":m (Mind)" is a heartfelt confession about the vulnerability and confusion that comes with unrequited love. The lyrics express the protagonist's longing for the other person to understand their feelings and reciprocate. The song begins with the protagonist asking how the other person is doing and shares that they are fine. However, the protagonist wonders when the other person will provide a longer response instead of the usual generic answer. The chorus emphasizes the protagonist's ignorance of the other person's feelings and self-perception as foolish for not recognizing the protagonist's love. It also acknowledges that the other person is "the best" and that the protagonist is willing to be available for them at any time. The lines "Tell me, Tell me, Mind" highlight the protagonist's desire for the other person to communicate their true thoughts and emotions. As the song progresses, the protagonist realizes that they don't need to be fearful or uncertain about expressing their feelings. They urge their heart (symbolized as "Heart" in the lyrics) not to beat too fast and overthink things. The protagonist hopes the other person realizes the impact of their words and understands the chaos it creates in the protagonist's mind. The bridge of the song introduces the idea that the protagonist doesn't have any further requests or expectations. They express their contentment and resignation with their situation. The lyrics convey a sense of longing and a plea for the other person to acknowledge their mutual foolishness in matters of the heart. In summary, ":m (Mind)" is a song that explores the complexities of unrequited love, insecurity, and the desire for open communication and understanding. It portrays the protagonist's journey of self-discovery and ultimately accepting their vulnerability and foolishness when it comes to matters of the heart.
