The lyrics of Lian Ross's song "Say You'll Never" portray the feelings of a person who has found true love and is deeply invested in their relationship. The singer begins by asking their partner to look into their eyes and tell them what they see - if there is any mystery or doubt, they want it to be cleared up. They acknowledge the power their love holds, as it has turned their dreams into reality and set their heart beating to their partner's sweet melody. The singer knows that their love is real, as they have felt it deeply since the day they met.

The chorus of the song is a request to their partner to promise that they'll never leave, using the repetition of "never, never, ever" to emphasize the importance of this assurance. The singer sees their life as being divided into two parts - before and after meeting their partner. They have moved from feeling like their life was just history without direction to feeling like they have control over their destiny because of their love. The singer emphasizes again the realness of their love and asks their partner to promise they'll never leave.

Overall, the lyrics are a declaration of a deep and enduring love, where the singer is asking for reassurance and commitment from their partner. There is an emotional intensity to the lyrics, with the repetition of "never" and the use of phrases like "deep inside my heart" emphasizing the strength of feeling.
