However, she still has feelings for her late husband towards Seiichi, her boyfriend with whom she is currently dating, and even when it comes to a physical relationship, she is unable to take a step forward. Just when I thought that things couldn't go on like this, Tsuneharu and Seiichi suddenly got into a fist fight. She is suddenly surprised and asks her why.
