Although it seems interesting it's pretty confusing mostly at the third and fourth chapter.The same happens with the other series of this author, which is called Kamunagara.But, Kamunagara has the mystery-supernatural element so it's logical to have some questions whereas this it's just a slice of life.What i didn't particularly like in those is mostly some lack of unification between the events.I recommend reading "Natsu no Zenjitsu" if you have the patience to wait for it to be translated...
