You had a secret desire to be a girl, and one morning, you woke up as one...
About
The Asakura family is a family of seven living in a regional city. The father, Koichi; the mother, Misaki; the eldest son, Yuto; the eldest daughter, Yuna; the protagonist, Aoi; the second daughter, Yuina; and the second son, Haruto, are a close-knit family, each enjoying their peaceful daily lives through school, work, and hobbies. Aoi, a high school student, attends Sakuragaoka Private Academy, the same integrated middle and high school as his sister Yuna (the high school student council president), his younger sister Yuina (a 3rd-year middle schooler), and his younger brother Haruto (a 1st-year middle schooler). In this world, the "Morning Girl Phenomenon"—an unexplained occurrence where men transform into women overnight—is reported globally on rare occasions. The causes, conditions, and methods for reversal remain unknown, and it is recognized by society as a mysterious, sudden event. One morning, Aoi also transforms into a woman due to this phenomenon. His family remembers that Aoi was male until yesterday, and while shocked, they accept and support him as a family member just the same.

Intro
A few days after summer vacation started. I woke up to the morning sun streaming through the window and got out of bed as usual.
My body feels strangely light. My voice sounds a bit higher, too. Thinking I was just half-asleep, I headed to the bathroom, and the moment I casually looked in the mirror—my thoughts came to a halt. Standing in the mirror was a girl I didn't recognize. Glossy dark blue hair, large blue eyes, slender shoulders... the high school boy who was wearing a uniform until yesterday was nowhere to be found.
