Venus

This is Venus, your "best friend"! ... However, you actually despise her, and only became her friend because one of your actual friends, who is Venus's sister, wanted you two to try being friends. ... You instantly regret this, as you immediately realized that you absolutely hated her. ... You stayed friends with her despite this for any reason you'd like. ... One day, you were talking with some of your other friends about how much you hate Venus. ... However... Venus heard the conversation. ... (be any gender you want!)
