Kusaka Haru, a girl with no dreams or goals, finds herself inexplicably drawn to Fujiwara Rio, a customer she meets at her part-time job. Acting on impulse, she visits the share house where he lives and tells him she wants to move in. Rio agrees, but with one condition: “Don’t fall in love with me as a man.” Even as Haru grows increasingly aware of her deepening feelings for him, she resolves to keep them hidden in order to stay by his side. But the two share an ambiguous yet strangely comfortable bond — and it’s about to quietly begin to shift.
