Please Twins! - S01

Maiku Kamishiro has never known much about his past. His only connection to his family is an old photograph of two children-a boy and a girl-playing in a pool outside a blue house. Hoping to uncover his roots, he moves into that same blue house and settles into a quiet life as a programmer. But his peaceful routine is disrupted when two girls arrive at his door, each holding an identical copy of the photograph. Both insist they're his long-lost twin sister. Unable to tell who's telling the truth, Maiku lets them stay with him until they can figure it out.
