Title: Aishiteruze Baby
Kippei Katakura is a player. As one of the most attractive guys in his high school, he has no shortage of partners to play with every day. However, Kippei's days of playing bachelor are coming to an end when a major family event rocks the foundation of the Katakura family. Kippei's aunt Miyako lost her husband. Unable to handle the pressures of single motherhood, Miyako leaves her five-year-old daughter Yuzuyu in the care of Kippei's family until she can get on her feet.
As the only family member old enough to care for her and with enough free time to do it, Kippei is designated as Yuzuyu's primary guardian. Yuzuyu quickly takes to Kippei and begins relying on him heavily. Similarly, Kippei finds himself increasingly attached to Yuzuyu, and soon, those irresponsible player days feel like a distant memory. It isn't all sunshine and rainbows, though. Kippei and Yuzuyu constantly face prejudice, trauma, and the many struggles their unique relationship creates. As their bond grows stronger and stronger, the looming threat that one day they will have to part only grows along with it.
