SOAV-017 A Married Woman's Cheating Heart Reiko Sawamura

It seems that she used to have night activities with her husband about three times a week, but at some point the number of times suddenly decreased. When I began to suspect that the reason was cheating, there was an incident that changed my suspicion to conviction. I happened to have the opportunity to drive my husband's car, and when I looked at the passenger seat, I found hair and accessories that were clearly not mine, and things that I thought were intentionally left behind by my cheating partner. What action did Mr. Sawamura take when he was shocked by the reality?
