I'm not Finnish, or a girl, or young, so my experience may not be relevant, but much of this felt unconvincing.

While the actors are generally pretty good and engaging, and some of the development felt real, for me there were too many drastic shifts in tone and attitude which, by the end, meant that it had lost believeability. For example, initially I was convinced by the emerging attraction between the ice skater and her girlfriend - but then they both take (for me) surprising sharp turns as a result of the relationship, such that the "happy ending" was not at all convincing. In addition, the third girl's combination of disastrous sexual encounters and very frank topics of conversation also didn't convince. With that level of "openness" about sexuality one would have expected her to have figured things out while alone before all the mishaps?

Also - a minor point, but given the combination of huge amounts of teenage bad behaviour, very sexual conversation and sexual situations, yet zero nudity I did end up wondering whether this was consciously targeted at the American market? It didn't feel European at all, really. Shame.
