Reading this manga turned out to be quite a pleasant surprise. I went into it not expecting much, but for a work of this kind, i.e. a short four-chapter long shounen ai manga, it is quite well thought out. The story's flow is good and is only about 30% fluffy. Even though it is such a short series, the characters and the plot seem to be fairly sound. I truly think that a lot of people can empathise with what's going on... and, I think that's what makes this manga such a fantastic yet simple piece. I would recommend Sono Yubi dake ga Shitteiru to anyone whois after a quick read.
