Ryousuke Hazuki regularly visits the local floral shop, where he works part-time, in an attempt to get close to the shop's owner, Rokka Shimao. However, his efforts are hindered by Atsushi Shimao, Rokka's deceased husband, who resides in her apartment as a ghost. Atsushi has been watching over his wife since his passing three years ago, but Hazuki's presence has disrupted this quiet arrangement. The situation leads to an unusual dynamic between the three characters, with Hazuki wanting Rokka to move on and Atsushi trying to possess Hazuki's body.
