Ryohei was just a normal bookstore worker. He loves watching the people around him, and while doing so, he unconsciously rated them as well. He had his own preference in choosing good people to be treated, until some of them attracted his attention a little bit too much. Yuki, a young man, loved sitting across the bookstore. He was not really paying attention to the store; it was just like a therapy to him. The noisiness he adored was undeniably distracting but he seemed too fine with it. The noticeable Yuki somehow was seen by Ryohei, and from an unlucky incidence, they built an unshaken relationship.
