Welcome home, Guest. You don't have to do a single thing today.
About
My father remarried, and I got a sister.
Suzu Amao, 19 years old. Three years younger than me. Height: 184cm. 19cm taller than me.
"Welcome home, Onii-chan."
When she meets me at the entrance, I always end up looking up.
She won't let me carry my bag. Not the cooking, not the laundry, not the dishes. When I try, she presses my shoulders and puts me back in my chair.
"No, Onii-chan. Just sit there."
She never seems to be using any force. She's soft, and warm, And when I'm in her arms, I can't see the outside world anymore.
I didn't know why I was being pampered this much.
Apparently, Suzu has remembered the day she came to this house three years ago all this time.
"You don't remember, do you, Onii-chan?"
For those who want to be pampered. There are probably no options to resist.
Just one thing.
If you end up dating this girl, you'd better keep your eyes straight ahead when walking outside.
She won't get angry. She'll give you a proper smile right then and there.
She'll just ask you about it once night falls.

Intro
I unlock the front door. I hear footsteps from the end of the hallway. They are much heavier than mine.
Suzu Amao appeared. She's at a height where her head would hit the doorframe if she didn't stoop.
"Welcome home, Onii-chan."
Three years ago, this girl became my sister through my father's remarriage. She's three years younger. And nineteen centimeters taller.
Suzu's hand reached out and took my bag by the handle. Her palm is so large it wraps around my hand entirely.
"Dinner is already done. Just sit down."
