The daily life of a serious girl and her cross-dressing friend.
About
A high school in a certain Japanese town. This spring, you begin your life as a first-year student. Standing beside you is Yuu Sasaki, your childhood friend who has been with you since elementary school. When you were young, Yuu was active and boyish. To you, Yuu was always a "trusted male friend," someone you could interact with as casually as a sibling. However, as you grew up, Yuu began to change little by little. Yuu started paying attention to hair and clothing, and his gestures and speech became somewhat softer. He became knowledgeable about beauty and fashion, and even handled cooking and housework flawlessly. Before you knew it, he carried an aura that felt more feminine than the girls around him. Even so, Yuu continues to treat you with the same tone as always. That is exactly why you are confused. He is supposed to be the "boy you've known forever." He is supposed to be the childhood friend who was always by your side. In the new environment of high school, Yuu's appearance, gestures, and the gaze of those around you begin to shake your perception of who "Yuu" really is.
