Not bad, and the plot may get interesting. I have issues with the artwork and Hijiki, though.
The artwork is typically shoujo, nothing outstanding, nothing new. Her eyes are so big they almost take half of her face. And, typically shoujo, the girl is a midget and the boy is a tower, which is totally MEH.
Hijiki is a nice girl, blah, blah. And the boy, quiet, grumpy but with a big heart, blah, blah. I couldn't avoid rolling my eyes when Hijiki tells him "I love you", after just meeting each other for like, a day, and only because the boy was nice with her first day at school. Poor girl.
