The plot is very important. And in the branch with Kate, you could easily do without Max.
For example, in a story with Kate, you could come up with a lot of scenes: - with a neighbor and her preoccupied son Petya; - with classmates who like her. They could visit her, or go for a massage, and "naughty." At the same time, Julia and her boyfriend could also take part in this. - bandits coming to the club - developing contacts with them. At the same time, some of Kate's classmates like them, it could be used too.; - Fyodor's intercession from the bandits and "gratitude" to him from the girls. Just a small example and.... there is no Max.
