@LOVELaisah okay let me tell you the ending:
1. Harry was gay
2. Blaire and Cade did not become a couple
3. Blaire fell in love with a boy in Texas named Riley
4. Riley was a jerk so they broke up
5. Blaire and Cade went to Harvard and finlly admitted their undying love.
5.2. They probably both became lawyers and had two kids.
