Title: Aishiteruze Baby
AKA: I Love You Baby
Author: Yoko Maki
Summary: Aishiteruze Baby is a shōjo manga series that revolves around the life of Kippei, a popular high-school playboy who flirts with any girl he sees, without thinking about their feelings. His life is turned upside down when one day his aunt abandons his five-year-old cousin Yuzuyu at his house. Kippei is assigned the task of taking care of Yuzuyu for the time being, and he must learn how to become the "mother" she needs. As Kippei learns how to care for Yuzuyu, he also learns to care for Kokoro, a quiet girl at his school, who helps him out.
In Japanese, aishiteru ze (愛してるぜ) is a casual, masculine way of saying "I love you"

Definitely Kippei and Yuzuyu in this one. There's no competition against them. Kippei starts out as a total playboy but then as he spends time with Yuzuyu has his cokking skills and personality changes a lot towards the better (yes, cooking skills and personality really did go together, trust me on this). And Yuzuyu on the other hand... Yuzuyu is sooo cute, it should be illegal to be that cute. Kawaii^^.
Have fun reading this one, it's another great read. But then again, i do only post what I think is good... I don't see the point in recommending something bad to anyone. Oh well, go have fun now. =D
