"Sie Weiß" (She Knows) is a powerful duet that dives into the pain and confusion of a toxic relationship. The song unfolds as a conversation between two lovers who are caught in a cycle of hurting each other. AYLIVA starts by describing her partner as someone who has lost his way, trying to find himself in other women and living in a different world. She points out that he's not being true to himself, saying, "Nobody knows you like I know you." She knows he's aware of the pain he's causing her, yet she questions why it's a problem for him when she decides to leave.
MERO's verse offers a confession, admitting his phone is full of other women and calling it an addiction. He acknowledges that he's the reason they can't make it work, even though he wants to be with her. Both singers express a mutual feeling of missing each other, but they are trapped by their pride and stubbornness. The song captures that heartbreaking moment when two people know they are wrong for each other but can't seem to let go, creating a push and pull of wanting the other to stay while knowing they should say goodbye.
