I really enjoyed this sweet but slightly messy story. Two boys, Tanaka and Nakata, accidentally get their papers mixed up due to their similar names. As they grow closer, they realize they have even more in common, from their heights to their meter dash times to their fashion and music tastes. But when Tanaka begins dating one of their classmates, Tanagaki, Nakata realizes that they may be more similar than he thought. 

I was a little unsure about this story at first. I liked the silly coincidences and I adored Tanaka and Nakata's friendship, but I was worried there was going to be some messiness with Nakata and Tanagaki. However, the story went in a lovely direction, and I loved all of the friendships in this story. There is a bit of cheating in this book, and though it's my least favorite trope, I think it was handled very well given all of the character's motivations and reactions, and the ending was satisfying for all of them. I'm really looking forward to reading more of Gorou Kanbe's work!
