【Rain Umbrella Parasol Office】My wife’s CG collection

I left my wife, Haruka, who is still in her first year of marriage, at our home for a four-month business trip overseas.
During this time, my wife and I only have contact with each other once a week.
During that time, the only contact I had with Haruka was once a week through a communication app that was available at the cheap hotels in our base.
In the meantime, I received a message from my boss, Professor
In the meantime, my boss, a professor, asked me to let his only son, Yuta, stay with us.
If you ask me, it seems that Haruka and Yuta are close friends. ……
