This is a secret memory that you will never forget. My husband's best friend, Koichi, came to our house on a business trip. Koichi, who was five years older than her husband, was like her husband's older brother. I also felt happy when I saw my husband rejoicing with a big smile at the reunion after a long absence. However, I was eventually attracted to the charm of Mr. Koichi as a man, which my husband did not have. The more I think it's useless, the more I can't suppress my burning desires.
