"Did you buy strange things at door-to-door sales again?" I was worried about going on a business trip from tomorrow because my wife, Erina, who is easy to be deceived because of her obedient personality.Because my father who loves women and my wife who is weak against pushing will be alone under the same roof since I was little.That said, the two of them are a family, so they're step-parents, so there's no way they could have a relationship...At that time, I had no idea that this sweet idea would cause a tragedy...
