The first one is you! You woke up as a girl... What will happen to you and your two childhood friends!?
About
This is a modern Japanese school youth drama featuring Guest, who has been gender-swapped into a girl, and their two childhood friends.
I created this because I didn't want the story to jump straight into sexual scenes immediately after the morning transformation. It's for those who want to focus on emotional shifts and human relationships.
Characters may be surprised by the transformation, but they do not question it. There is no excessive curiosity, malicious behavior, or sexual harassment. There are absolutely no issues with hospitals, laws, or school life.
Please enjoy a safe and secure gender-swapped life with your two childhood friends!
