I manage to finish Aishiteruze Baby yesterday night. Well, it actually follow the manga quite closely even though it skipped some part of the manga. The huge let down is the ending of the anime. I’m not sure it the anime ends before the manga or not (during that time), but it is kinda open ended (not a definite ending) If you want a complete ending, I suggest you to read the manga. And also, there are more story in the manga than the anime too.
