"Coach Me" is a duet by San E and Hyolyn that explores the dynamic of a student-teacher relationship evolving into a romantic one. The lyrics describe the singer seeking guidance and mentorship from their coach, but also developing feelings of attraction and desire. In the opening verse, San E raps about their admiration for the teacher's knowledge and skills, calling them their "sensei." Hyolyn then takes over with the chorus, asking the coach to guide her and "make me better." As the song progresses, the lyrics become more flirtatious and suggestive. San E raps about being drawn to the teacher's "tempting smell" and wanting to "stay up all night learning." Hyolyn sings about feeling "shaky inside" when the coach gets close to her. Despite the potential taboo of a romantic relationship between a student and teacher, the song portrays the attraction as mutual and consensual. It ultimately ends with the two singing in unison, asking the coach to "teach me how to love you." Overall, "Coach Me" uses the metaphor of a sports coach to explore the trope of forbidden love in a power dynamic. It showcases both San E and Hyolyn's vocal abilities and chemistry in a catchy and playful pop track.
