枫桥夜泊

作品主要围绕犀川研究室成员之一的犀川创平，以及犀川的恩师的女儿西之园萌绘两人展开，虽然萌绘并不是犀川研究室的成员，但参与了该研究室此次的研讨旅行，地点定在了妃真加岛。随后，在萌绘的提议下，犀川和萌绘前去拜访了座落在这座岛上的真贺田研究所，然而他们在那里的密室中发现了一具尸体。以此为契机，之后又连续发生杀人事件，被卷入其中的两人一同解决充满谜团的连环凶杀案……。Would you fall in love with a person whose voice you haven't heard for months, whose face you haven't touched, you can't smell, you don't even have the chance to pass by the same street, you can't even be in the same photo, who is miles away from you, even by seas, islands and cities。
