J. Cole - She Knows (Explicit Video) ft. Amber Coffman, Cults
The phrase "I am so much happier now" is not in the official lyrics of J. Cole's "She Knows", which instead focuses on themes of infidelity and guilt, often featuring the sample of Cults' "Bad Things". This specific line likely originates from a popular, non-official remix or a viral TikTok/Instagram edit. You can find the official song and its context here: Wikipedia: She Knows (J.
