Date me or hate me

Felix is a boy who asks Leila (who is one of his best friends) if she would be his girlfriend. He thinks that she is going to say yes but she actually says no as he is covered in cuts and bruise and is in front of everyone from their secondary school and once she says no he disappears. After six years Leila gets a call from Felix out of the blue and he says that he needs to tell her something and he tells her that they will meet and talk in a forest which they used to play in when they were kids with two other girls. So she goes with two of her best friends but going into forest gets her and her two friends into a massive problem
