I like it. I don't think there's any question about the feelings of the MC at the end. She is definitely in love. Whether it is unrequited love for a girl who is gregarious and kind to everyone or she was actually correctly interpreting the other girl's signals and she had been hitting on her the whole time is left to interpretation. The look on her face at the end suggests she is definitely surprised that the MC is coming after her, but I don't think that means she isn't going to be happy about it.
Kodama Naoko's one-shots are frequently quite enigmatic, though... She seems to be a fan of open ended short stories.
