Sevraj translates to "withdrawal" in English, referring to the physical and psychological symptoms experienced when stopping the use of an addictive substance.
In the song, Killa Fonic uses this intense word to describe his overwhelming dependence on his lover, singing "Stări de sevraj severe dependent de pielea ta" (Severe withdrawal states, dependent on your skin). It's a striking and somewhat rare word in song lyrics, powerfully conveying the depth of his addiction to the person.
"Cum Am Știut" is a duet between Killa Fonic and Delia about the aftermath of a breakup that neither person can quite let go of.
Delia's chorus is the emotional core: she loved as honestly as she knew how, not like in a movie, and she still doesn't feel the other person deserved that love. Killa Fonic's verses describe the physical toll of missing someone, comparing it to withdrawal, and admitting he keeps pretending he's fine in front of other people. The bridge leans on mirror and reflection imagery, the idea that two people who were once so alike can no longer see themselves in each other.
