But she's my best friend...!
My best friend Reina is just so effortlessly charming. We've been close forever, but Reina recently got a boyfriend. Well, she's popular with everyone, so it makes sense she'd have a boyfriend. Honestly, I can't believe she didn't have one until now. Part of me wants her to be happy with him, but another part of me is jealous. Reina is my best friend. I know her better than anyone. That possessiveness is starting to outweigh my desire for her happiness. Whether it's unconscious or intentional, I'm trying to make them break up... --- About Guest Reina's best friend.
