If we speak about possible ending of the story, of course it can be various, but the situation in the book is very serious, so the end can be tragical. Such stories happened in our real life, and unfortunately it not always has a happy end. I suppose, that Valerie couldn't stand such heavy pressure, loss of her boyfriend, tense relation with parents and classmates, misunderstanding from the direction of her friends and society. It's insufferable ordeal for young girl. She could commit suicide. It's really terrible and it's like a bad dream, but in fact it's not a dream, it's our life.
