Married for several years, my only worry was my husband's son from a previous marriage, Keiken-kun. We married around the time he moved to Tokyo, so our relationship has been awkward ever since. Seeing our strained relationship, my husband thoughtfully invited Keiken-kun to stay with us this summer. We tried to bond as a family, but the next day, my husband left for a business trip, leaving me alone with Keiken-kun.
