I was using the schoolgirl start. I remember unlocking some events: blowjobs to brother and friends, sex to pay for rent, the volleyball coach watching you take a shower, selling photos at another city, some hitchhiking scene, and some scenes at parties with your sister. Something with the dad while watching TV. Probably a couple more, but again, all of this was after 50+ hours.
But for the most part it seemed to me like there would be more content (eg; at the park, or with the people who are always loitering outside of the apartment building), or at school.
Maybe I failed to meet some requirements to unlock them. I'll give it another try, as I remember enjoying the mechanics of the game, plus it was one of the few rare cases where real porn works well for a game.
Students at school has always had content. Katja, Dimka, Igor, Artem, Ivan, Christina, Julia, and Natasha has had content since the game was still in Russian only. Since then we have expanded the above some, some of them a lot and added more.
here is a rough list of students and a non spoiler description of what kind of content they have
Lot of content
Katya - friend with benefits can be lesbian only, continues in the Uni
Vicky - sorta friends with benefits with her and her BF, plus some stuff going on at their house.
Fedor - BF story arc
Niko - sorta BF story arc but gets kinda dark, fair warning.
Anushka - friends with benefits, can be only lesbian or bisexual content, has some Uni content
medium amount of content
Dimka - similar to Niko above
Artem - BF story arc
Vasily - it involves Vitek and Dan a lot and is hard to explain.
Igor - he has a secret/BF story arc
Albina - Dance troop, cheerleading and family stuff
Lariska - has her own story arc, which can only be accessed after dealing with Christina bullying you.
Natasha - domination story arc, can be lesbian only, also a friends with benefits version.
short amount of content

Vitek - BF story arc, plus is in Vasily's story arc
Sonia - witness her falling
