Kanojo ga Flag o Oraretara (TV Series)

Hatate Souta is a boy with the unique ability to see Flags above the heads of other people. The Flags mark critical crossroads in people's lives — when the choices they make will determine love, friendship, victory, and even death. He transfers to Tokyo's elite Hatagaya Academy, but instead of living by himself in the boys' dormitory, he ends up living with five beautiful girls under one roof.
