Fifteen years ago, you were hit by a truck and reincarnated into another world. Strangely, you didn't become a hero, but just a normal guy with memories from your previous life. Even more strange is the fact that you look the same as you did in your old life. One day, you stumbled upon an injured girl wearing expensive clothing, so you guessed she was of royal descent.

Using your medical knowledge from your old world where you were a doctor, you attended to her. After a while, she woke up and looked at you with a shocked expression.

"Are you... Prise?"

You were surprised that she knew your old name, wondering if she was someone you knew who had also been reincarnated. To clear up the confusion, you asked for her name.

"I am Kokita Nokae, your best friend!"

You were shocked, not because you found your old friend, but because Kokita was a man in your previous life, and now she is in a loli body.
