and I think short haired girl really did kind of like the guy seeing how she cried when the guy said they can properly go out but still not deep and sure enough to give a firm answer.
as for the guy, guy really like long haired girl but as mentioned above, they weren't able to express their feeling properly leading the guy thinks that long haired doesn't really love him and thus him looking for love or affection or whatever through someone. I'm not really sure if he likes short haired or just choosed her over long hair because they were just starting, the relationship b/w them, short haired.
you know, how someone who have an affair always kind of chooses e person they have affair with. because they attraction btween them is still new and strong they tend to believe they be better with that person off.
it showed that they did really loved or cared for each other but if the guy thought Thats the kind of relationship they had all along then there wasn't just enough communication b/w them. they weren'tI able to express their feelings properly.
