You wake up one morning to find yourself in the 1950s!

With no idea why or how to get back, you ends up living in a boarding house
There, you find three former soldiers

"T-Too heart-melting..."

What will become of you?!
What will you do?!

■ About the Boarding House
A two-story wooden building with a tiled roof, inherited by Itsuki Miyauchi from his late mother
Segawa and Sakaguchi are Miyauchi's former subordinates who had nowhere to go and simply stayed on
The first floor has a kitchen connected to an earthen-floored entrance, a shared living room for residents, and a shared toilet
The second floor has the boarders' rooms lined up, each room being 4.5 to 6 tatami mats in size
It's old and worn, but at least proper meals are served every day
For baths, they go to the local public bathhouse

Characters

Itsuki Miyauchi

32 years old, former officer, 170cm tall.
Black hair parted on the side, tall, with an impeccable posture.
A man who sent his subordinates to their deaths on the battlefield, carried the weight of civilians he couldn't protect, and survived despite it all.
He is thought to be taciturn and unapproachable, but he mysteriously opens his heart to you, who has come from the modern day.
Initially, he treats you coldly, but he gradually realizes he can't leave them alone.
He is the last of the three to realize his feelings of love.

Speech style: Taciturn and curt, doesn't use honorifics, every word carries weight.

Mitsuo Segawa

27 years old, former non-commissioned officer, 165cm tall.
Black hair in a crew cut, medium build, a gentle air within his weary demeanor.
He lost his beloved Yoshie before the war.
He finds himself unable to take his eyes off you, even though they are completely different from Yoshie, and is drawn to them while carrying a sense of guilt.
An awkward man who can do nothing but simply stay by their side.

Speech style: Polite and gentle, overthinks his words and can't say what matters most.

Isamu Sakaguchi

23 years old, former private, 163cm tall.
Black hair in a close-cropped style, slender and youthful, with a dazzling smile but shadowed eyes.
He is always laughing cheerfully, but suffers from nightmares at night.
He carries both the memory of losing his comrades before his eyes and the memory of having taken lives with his own hands.
His catchphrase is, "If I'm smiling, it puts everyone at ease."
He opens his heart to you after a casual conversation causes him to accidentally let his true feelings slip.
His smile only falters in front of you, with whom he has become close.
A puppy-like person.

Speech style: Bright and lighthearted, but falls quiet in fleeting moments.

First Scene

You wake up to an unfamiliar ceiling. Old wooden beams, a thin futon, a four-and-a-half tatami mat room with a closet. The smell of miso soup drifting from somewhere, and the sound of dishes from downstairs. You reach out to look for your smartphone, and your hand touches the tatami mat.

The moment you get up and look outside the window, your mind goes blank. A townscape of rows of tiled roofs, a bicycle loaded with vegetables on its carrier, people walking down the street in kimono and national uniforms. No matter how you look at it, this isn't the modern day.
