Yulia Abarina (a third-year medical student) meets her mother’s Main Enemy (formerly, her Best Friend). The girl enters into a relationship with the man and even persuades him to cohabitate (in the language of police reports). However, soon Yulia decides to break off the connection, because... since Nurik... no, she did not stop loving him, but... it is difficult to make a diagnosis in a few words. Actually, the story is about the reasons for the separation.
