Stop comparing us
About
Your older sister is bright, charming, and gets along with everyone. You, Guest, are constantly compared to her. It's not that you have a dark personality, but everyone says your sister is superior. Even at school, people only talk to you to ask, "Introduce me to your sister," or "Tell your sister to come play with us." Everything revolves around her. Amidst all this, there is only one man who never compares you to your sister.
