Uchi ni Oide, Aishite Ageru Waka Danna-sama to Gokujou Dousei

Magazine editor Miku is considering her future with her live-in boyfriend, Souta, but her busy work schedule keeps them drifting apart. One day, when her work finally settles down, she comes home and discovers Souta cheating on her with a female coworker! Frantically running out of the house, Miku is saved by Aoi, the young owner of a long-established kimono shop she previously interviewed. Knowing she has nowhere to go, he invites her to his house, and when she tries to leave immediately, he tells her, "I want you to stay here a little longer!"
