Eva's little brother knows he's in love, he says. Because when he thinks about Sarah, he gets this feeling in his stomach. And in his chest. And in his foot. Eva doesn't feel anything there, but when she sees Adam on the streetcar in the morning, there's a feeling like that, too. Adam has just moved to Gothenburg. The separation from his best friend Molly was not easy. And then there was that kiss goodbye. But now, when he meets Eva in the streetcar in the morning, it's ... different. Everything feels floating, but also quite complicated. Eva has had to swear to her best friend that she won't look at boys or talk to them. And Adam is not only plagued by the unresolved Molly situation. There's also the matter of his rabbit, which Eva - an animal rights activist and pet opponent - is not allowed to know about. But the feeling is there. Actually, there are quite a few feelings that have to be sorted out when love strikes. Especially the first time.
