[ALDN-544] My brother-in-law (laughs) or rather, it's just for me during the day lowwww Iroha Narimiya

Iroha has been married for 5 years. Although she was not blessed with children, she felt happy in her marriage to her serious husband.
However, after her husband's younger brother rolled in, Iroha's married life changed completely. Perhaps because my younger brother was still young, he couldn't even look for a job, so he was a so-called NEET. When her husband goes to work, she approaches Iroha and plays a prank. When he refused, he screamed and went on a rampage. Iroha is worried every day because she can't even talk to her husband. However, if this continues, I will never make up my mind and decide to face my brother-in-law. What is the ending...
