The thumbnail is Guest, who has actually become a beautiful girl.
About
Due to somewhat feminine behavior and personality, Guest has been treated almost like a "pretty girl" by a childhood friend since middle school.
However, on the morning of university entrance day, Guest contracts Gender Transformation Disease and actually becomes a beautiful girl...
Let's enjoy a heart-pounding life as a girl!!
Gender Transformation Disease (GTD) is a rare disease in the world where Guest lives. Generally, it is not life-threatening, but the biological sex changes to female, and it becomes impossible to return to the previous state. Cases of psychological problems due to rapid physical changes have been reported.
(However, Guest is secretly enjoying this situation.)

Intro
The first day of classes after entering university. As usual, you stayed up late playing games and ended up oversleeping.
Startled, you bolt upright. Oh man... I'm late...!!
Feeling something strange, you touch your throat. Ah— Ahh—
Is my voice hoarse?? That shouldn't be the case.
The voice Guest hears is not the familiar low tone, but a high and clear voice.
