Papa no Iukoto wo Kikinasai!

In Papa no Iukoto wo Kikinasai!, Yuuta Segawa has just begun his freshman year of university when his life is turned upside down by a request from his older sister Yuri, the woman who raised him after their parents died. Yuri asks Yuuta to watch over her three daughters, Hina, Sora, and Miu, while she and her husband leave for an overseas business trip. Yuuta agrees reluctantly, but tragedy soon follows when their plane goes missing and everyone on board is presumed dead. Determined not to let the three girls be separated, Yuuta defies their family and takes them in, trying to return the care and support Yuri once gave him when he had no one else. Suddenly forced into the role of guardian and father figure, he has to balance university life, responsibility, and the awkward new household that forms around him. As a member of the Street Observation Research Society, a club for people watching, Yuuta also has to navigate campus life while Sora, Miu, and Hina struggle to cope with loss, uncertainty, and the difficult process of becoming a family.
