In Duman's song "Seni Kendime Sakladım", the lyrics revolve around the theme of not caring about what others think or say and prioritizing one's own feelings and beliefs. The singer asserts that they do not involve themselves in gossip or drama, and they are not interested in pleasing everyone or being "bought and sold". They have kept someone special to themselves and have figured out everything on their own. The chorus repeats the line "Seni kendime sakladım" which translates to "I've kept you for myself" as a declaration of their deep attachment to this person.

The lyrics suggest a sense of confidence and independence, as the singer is not swayed by external opinions or pressures. Instead, they have made their own decisions and are proud of them. The repeated use of "isterlerse" which means "if they want to" is a powerful statement of agency, as it emphasizes that the singer is not bound by anyone else's expectations or needs. The use of the word "meydan" which means "field" or "arena" also adds to the theme of standing up for oneself and facing challenges head-on.
