For the Beheading

These two detective stories revolve around beheading. A headless male corpse is discovered in a locked room at an art gallery, and all four people present are suspects. After examining the scene, someone realizes that the killer's motive for decapitating the victim is far from ordinary. At a school, a male corpse with its head severed appears at the site of a couple's confession, and the air is filled with the scent of flowers. One part of the corpse is also strangely attracting people's attention. In both stories, uncovering the killer's motive for beheading their victim is the key to finding a breakthrough in the case!
