Tsumugu Kikka, a 28-year-old woman, lives alone on the second floor of an apartment building and works from home as a wasai, producing traditional
Japanese clothing. Her work is commissioned by Mashimo, her high school ex-boyfriend, who still lives exactly 200 meters away. Kikka's quiet routine is disrupted when she is unexpectedly selected to serve on the apartment complex's management board, where she meets Hirara, a man who lives 200 meters directly above her in the same building. As Kikka's interactions with Hirara increase through apartment-related duties, unresolved feelings connected to Mashimo resurface, placing her at the center of a horizontal and vertical
romantic triangle. ==Publication==
