Erika Kitagawa works at a lesbian bar, but is married and has a daughter (Ikumi Kurokawa). - However, the marriage was only a formality, and the daughter was her husband's stepchild. - Currently, my husband is working overseas and his living hours do not match my daughter's, so we do not have a chance to see each other as a family. - The two only meet on weekend hot spring trips. - For some reason, Ikumi is looking forward to going on a trip with Erika.
