Aishiteruze Baby

This is a shojo manga series with an anime adaptation.

Kippei Katakura is a lazy high-school playboy. He returns home one day to find that his sister has charged him with the upbringing of his five year old cousin Yuzuyu. Yuzuyu's mother couldn't stand the stress of raising her as a single parent and (at least temporarily) can't handle being around Yuzuyu. Kippei takes up the task with great gusto, and the series deals with his development as he cares for Yuzuyu.

The series alternates between Yuzuyu at pre-school, Kippei at high school, and their life together at home, and is chock full of heartwarming moments.
