Manga artist Mizuno Himari has hit rock bottom: her childhood friend stole her fiancé, her manga project was rejected, and she lost her housing. Needing a place to stay, she moves into a share house designed for creative professionals. Her new housemates are the wary novelist Yuzuki Shizuto and the sociable designer Okamoto Aki, so she finds herself sharing a home with two men.

During the first‑night welcome party, Shizuto develops a misunderstanding about Himari’s character. To clear the air, she drunkenly visits his room, and the encounter takes an unexpected turn. This awkward beginning sets off a series of developments as Himari and Shizuto navigate their growing feelings amid the close quarters.

The story’s first major conflict arrives when Airi, the childhood friend who stole Himari’s fiancé, targets Shizuto by getting close to him. Himari must confront her past betrayal while protecting the new relationship she is building.

Later, after the Airi situation settles and daily life in the share house returns to normal, a new resident appears: the cosplayer Yuki‑chan. Yuki‑chan’s flirtatious attitude toward Himari introduces fresh complications and tests the bonds forming between the housemates.

Through these narrative arcs, the series follows Himari and Shizuto as they come to recognize their mutual feelings, culminating in a resolution that brings the shared household to a warm conclusion.
