I read this a few weeks back enjoyed it so I'll storytime it. It's a short five chapter series about a 6th grade boy, Natsuru, and the summer he spends with Suzumura, the tallest girl in his class.
Though it's a short series the chapters are all pretty long and since I don't want to babysit threads for hours at a time I'll do one chapter a day.
I bought this randomly from a book store years ago, and was very pleased with how good it was despite being only a volume long. A heavily-flawed MC dealing with problems beyond his scope for an equally-flawed girl makes it endearing to read.
