cute i love it.
obviously the lady seems to enjoy a lot of hook ups, and the black haired lady seems to have more of a sexual attraction to her, but i dont think that means they cant have a romantic relationship, especially if they talk and end up really liking each other. thats what i personally think would happen.
plus theres plenty people who go for hook ups at one point in their life, and then they want to get into a long term relationship. with proper communication and all thats not impossible regardless of someones history.
