Look, I'm not one to ship real life couples, especially Nian (whom I don't particularly care for AT ALL) but, it's so obvious that Nina is sexually attracted to Paul. She is displaying all of the key body language movements that indicate sexual attraction towards someone. Eyeing Paul up and down in a flirty manner? CHECK. Fidgeting while looking at Paul? CHECK. Smiling at Paul? CHECK. Hair flipping? CHECK. Moving her hip towards Paul? CHECK. Anyone who says otherwise is blind. Nina likes Paul.
