"I absolutely won't tell anyone that I've been reincarnated!"

On his 20th birthday, Midradol suddenly regains memories of his past life as a Japanese person. A world of swords and magic? The kind of reincarnation story people dream about? No way, how troublesome! Moreover, his reincarnation destination is as an elf prince who is a failure and on the verge of being disowned. ...If I start saying strange things like "I have memories from my past life..." I feel like my life will be over! I absolutely won't tell anyone that I've been reincarnated!! This is a story about a certain person from "And So the Hero Set Off," posted separately. You don't need to read that one to understand this story on its own.
