I've been married for five years, and my husband, who runs a company, is a patriarch with an old-fashioned male mindset. He thinks that making money is the most important thing, but I felt suffocated and blocked in a life without love from my husband. In the midst of this, I felt like I was freed from the cage only when I was talking to Hosoda-kun, the second generation owner of a private store that I've been using for a long time... I was Kokoro by the kind behavior of this innocent young man, and I cheated on him for the first time in my life.
