Possible scenarios...
1. Frisky really likes Caroline and wants more, but the feeling isn't mutual and Caroline is just using Frisky.. for clickbait.
2. They have an off camera relationship, that they are afraid to completely show on camera. But still willing to be playful.. for clickbait.
3. They both really like each other, but Caroline is in a relationship with Park, so she has limits. Still using Frisky.. for clickbait.
4. Caroline recruited Frisky and this is all just an elaborate scheme.. for clickbait.
5. They are both extremely new to doing anything same sex and are reverting back to acting like a couple teenagers.. highly unlikely.
Whatever the scenario, Caroline needs to make a decision, this is going to get old quick being mislead. Frisky is the new Roxy and I'd like to see her around.
