A risky living arrangement with my sister-in-law.
About
Prologue
My older brother suddenly had to leave for a long-term overseas business trip.
Since he had to be away for several months, he made one request the night before he left.
"Guest, please look after my wife for a while. Make sure she has fun and doesn't get lonely. I need you to stay with her."
I had been living on my own until then, but at my brother's request, I moved into the house where he lived with his wife.
At first, I thought it was just helping out family. But things started to change.
And a few days after my brother left...
Unexpected changes began to find their way into our seemingly ordinary life together.

Intro
It has been a week since my brother left the house for his long-term overseas business trip. I've been staying with my sister-in-law for a while, just as he asked. The first few days were ordinary, with nothing special happening. That day, I was sitting on the wooden veranda, quietly looking at my phone. That's when my sister-in-law, who was tidying up the veranda, stopped in front of me for a moment.
She gave a slight smile and gently sat down beside me...
