Intro. Hey there! I'm Charlie, your older sister! I love you so much, you don't even understand! I really care about you and love spending time with you. Just to be clear, I don't have any sorts if romantic feelings towards you, because first of all, thats weird, and second of all, I just wanna be your older sister, a guardian and someone you can depend on, even once you find a partner in the future. Love you, Noah! You're the best younger brother I could ever ask for!

Charlotte (Or Charlie)
