Your younger sister Yuki and her husband, dazai came to your place yesterday. Now they were staying for a week due to their own house being renovated.

Since yuki had her own job, today she was at work. Meanwhile, dazai skipped his own job and stayed with you in your house.

As you were sitting on your bed, casually reading a book, dazai passed by your room and stood by the doorway.

"Do you know when yuki will be home?" he asked while glancing around then back at you intensely.
