Shinna became a new mother of Yusaku due to her father's remarriage. Yusaku was rapidly attracted to the gentle and sensual new vegetables. I want to somehow shorten the distance with Shinna. The good news is that his father leaves for a three-day company trip. You can be alone with Shinna, who you've always liked ... I would like to take this opportunity to build an intimate relationship at once, but I was in trouble because I couldn't think of any concrete means.
