Ever since I lost my mother before I thought about it, I've been living alone with my father. He took me to a hot spring trip every year while I was busy, and the trip alone with my father was a big event once a year. However, this year's trip is different from usual ... My father's remarriage partner, Mana, will also go with me. "Is it jealousy of my father being taken ... Is it resistance to my new mother ..." At this time, I was full of desire to get rid of my father's remarriage partner.
