Our Little Sister (2015)

Three sisters have their lives turned upside down by the arrival of a half-sister in Our Little Sister (2015). When their parents divorce then leave to be with other people, three sisters move into their late grandmother’s house and happily live together. Several years later, when they are all young adults, their dad dies. His widow is deemed an unfit mother so they allow their 13-year-old half-sister whom they barely know to move in with them. With very different lives and expectations, comedy and drama ensues. Haruka Ayase lets us see her get dressed in the morning when she walks into a room in just her bra and a pair of jeans. We get a good look at her cleavage and tight abs as she pulls on a shirt.
