Unlike the more popular Love Hina, Angel Tales and Ai Yori Aoshi center around a male who is doted on by his female companions rather than drearily beaten up in each episode. Music is used to great effect and a caring atmosphere is generated in both which doesn't fit neatly into the bog standard harem genre comedy that most anime fans would be used to.

In both Angel Tales and Happy Lesson, a boy is taken care of by, in one case, a group of angels; and in the other case, a group of teachers. This of course causes some commotions and leads to funny situations. Both anime give a similar feeling, so if you liked one, you're likely to appreciate the other one too.

Their are many similarities between Angel Tales and Sister Princess. They both feature a man who suddenly finds himself having to support not only himself, but also 12 girls/women who claim to have a past connection with him but offer little to know proof of this relationship. Despite this they choose to share a home with them and try to make them happy.
Both anime have a boy that suddenly becomes surrounded by tonnes of girls that want nothing more than to make him happy by any means. Angel tales is more fantasy as the girls are angels of his past pets where Sister princess is just about a boy who suddenly gets lots of sisters. Mindless cuteness and random acts of sillyness prevail! If you liked one check out the other.
