Life's all about having fun and laughing with your friends, isn't it? But when Chiba's suddenly enthralled by someone new, what will become of Ginko? 

3rd story: Umemiya Shino and Sugahara Kyoushiro - Kyoushiro, waiting in the apartment he once shared with Akari and, later, with Shino, pines after his lost love. At least, he isn't alone...
