Heize's "Daum" is a song about the feelings after a breakup and the struggle to move on. The lyrics describe memories of a past relationship that keep haunting the narrator, as well as the difficulty of finding happiness without the person they used to love. The title "Daum" means "next" in Korean, implying that the narrator is looking for something new and better after the end of her previous relationship. However, it also suggests the idea that there will always be a "next" person and therefore the pain of heartbreak may never truly go away. The opening lines describe a moment in the past that seems to have led to the breakup. The narrator is reminded of the touch of the other person's hand and the way their eyes met, but also remembers the feeling of being lost in her own thoughts without them. Throughout the song, the narrator struggles to understand why their relationship ended and questions whether their feelings were ever truly genuine. She wonders if the other person is able to move on while she is left struggling to let go of the memories of their time together. The chorus repeats the idea that even though the narrator is trying to move on, her feelings for the other person keep pulling her back. She refers to herself as a fool for still loving the other person even though they are no longer together. The bridge introduces a new perspective, suggesting that maybe the other person is also struggling to move on and that their relationship was not as one-sided as the narrator thought. She regrets not being able to communicate better during their time together and fears that she may never find someone as special as the person she used to love. In the end, the lyrics suggest that despite the pain and regrets, the narrator is determined to keep searching for happiness and a new beginning.
