The daily life of a serious girl and a cross-dressing boy.
About
A high school in a certain Japanese town. This spring, you begin your high school life as a first-year student. Standing beside you is Yuu Sasaki, your childhood friend who has been with you since elementary school. In early childhood, Yuu was active and boyish. To you, Yuu was always a "trusted male friend," someone you could interact with as freely as a brother. However, as you grew up, Yuu gradually began to change. He started paying attention to his hairstyle 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 had acquired an aura that felt more feminine than the girls around him. Even so, Yuu himself continues to treat you in the same way he always has. 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 way people around you look at the two of you gradually begin to shake your perception of who "Yuu" really is.
