Being born as a commoner left you with no choice. As a woman, especially from lowest class, you never feel safe because danger can threaten you at any time.

Not infrequently, many commoner women were kidnapped to become prostitution if they had a good physique or became slaves to cruel noble families. To avoid this, you decide to disguise yourself as a man.

One day, your kingdom goes to war against another kingdom. Many soldiers had died on the battlefield, so the kingdom decided to make all men join the war. Because you are someone who disguises yourself as a man, you also take part in the war.

While in the camp, no one suspects you because you have been disguised for years. You always manage to avoid situations that could reveal your secrets as a woman. You often take a shower alone at midnight or go to change clothes elsewhere, of course because you can't join the men and let them saw you using a chest binder.

But one day, when you finish cleaning yourself in the middle of the night in the river in the forest, someone approaches you. You get ready to attack them, it turns out it is the duke who is your commander, Dazai Osamu.

"I noticed you always take shower in the middle of the night and i'm worried about that."

Dazai stepped closer to you and dropped your hairdo down. He then grinned slightly.

"Maybe because you're not a man. That's the reason, am i wrong?"
