The song "음 (Mmmh)" by KAI (EXO) is about a person who is deeply in love with someone and wants to protect and possess them. The lyrics suggest that the protagonist has a negative quality about themselves that drives them to want to take everything from the person they love. The lyrics also allude to the idea that the person they love now belongs to them and they must protect them from jealousy and other external forces.

The lines "내가 너무 나빠서 네 맘을 전부 빼앗고 싶어져" (Because I'm so bad, I want to take everything from your heart) imply a sense of inferiority and fear of losing the person they love. The chorus "You make me feel so (Mm-mhm) 숨을 내쉬고 뱉어 like (Mm-mhm) 경계를 넘어서 like (Mm-mhm) 내 품에 널 안아 like (Mm-mhm) 다른 생각은 하지마" (You make me feel so (Mm-mhm) Breathe it in and out like (Mm-mhm) Cross the boundaries like (Mm-mhm) Embrace you in my arms like (Mm-mhm) Don't think about anything else) suggests that the protagonist only wants to experience the present moment with the person they love and doesn't want them to think about anything else.

Throughout the song, the protagonist expresses their desire for the person they love, using metaphors like "The scent of a flower, girl, is this yours?" and "그들의 질투가 네 몸을 떨게 만들어" (Their jealousy makes your body shake). The lyrics also imply a sense of possessiveness and control over the person they love, as heard in the lines "그냥 내게 (안겨) 원하면 날 망가뜨려" (Just snuggle up to me, if you want, destroy me).

Overall, the song "음 (Mmmh)" portrays the complex emotions associated with the intense desire and possessiveness that come with deep love. The lyrics suggest that the protagonist is completely consumed by their love for the other person and will do anything to protect and possess them.
