Morisato Keiichi has always had bad luck. No matter what he does or how he acts, nothing seems to go his way. His bike frequently breaks down, his classmates take advantage of him, women ignore and scorn him, and on top of all that, he’s only 5'3". In Heaven, when someone’s bad luck and good luck are so heavily out of balance, Belldandy (Goddess First Class, Second Category, Unlimited) of the Goddess Assistance Agency comes to the rescue. Belldandy grants Keiichi one wish to make up for all of his bad luck, but when Keiichi wishes for Belldandy to stay by his side forever... the trouble begins. Can Keiichi keep Belldandy by his side, or will outside elements force her to return to heaven?
I will go on record as saying the farther I got into Ah! My Goddess the less I liked it. However this recommendation mainly deals with the early parts of Ah! My Goddess and you can decide for yourself from there. Lovely Complex is so enjoyable because of the way the two main characters play off of each other. Much of the same can be said about the main characters in Ah! My Goddess who have a great relationship thats enjoyable to watch
Yuuto Ayase is not interested in girls - if his two housemates are anything to go by, girls are loud, brazen slobs that are best left alone. However, when Yuuto accidentally discovers an important secret of his school’s most popular female, Haruka Nogizaka, the two become bound in a budding friendship. All too soon, Yuuto discovers that, despite her flawless appearance, Haruka is clumsy, naive, and a closet otaku... and he just might be falling for her.
Tomoya Okazaki is a third-year high school student who is generally bored with life and doesn't take his studies, future, or anything else seriously. One day, however, he meets a lonely-looking girl in the school courtyard, Nagisa Furukawa. She explains to him the source of her loneliness: she had missed a lot of the previous school year and thus is repeating her third year; everybody that she knew has already graduated, and she is lonely. Tomoya is rather indifferent at first, but decides that he has nothing better to do and spends increasingly more time helping Nagisa restore the school drama club. As his relationship with Nagisa grows, Tomoya begins to open up to various other people around the school as well...
Though it may be a bit weird to recommend Lovely Complex to Clannad, I think fans of the comedic timing of Clannad will surely enjoy this too. Though Clannad is a bit more on the dramatic side, but we cant hide the fact the it has some awesome comedy too, if you enjoyed Sanae-san and Akio's antics, and how everyone picks on Sumehara, you'll definitely enjoy Lovely Complex (and vice versa).

To make matters worse, he's quickly befriended by Natsumi, a towering yet kind girl who takes an immediate liking to the boy.

When Ritsu was in high school, he fell in love with a boy who broke his heart, changing his view of love forever. Now a jaded adult, Ritsu has just transferred to the Marukawa Shoten company in hopes of publishing literature, only to be told that he'll be working in the shoujo manga division instead. What's worse, his boss is brash, rude and seems to have an interest in him! However, the biggest surprise is yet to come for Ritsu, as he soon discovers that his boss is none other than his lover of his past!
Both animes have similar, little naive atmosphere, making them very likeable, although there are big differences since in Lovely Complex main characters are high-schoolers (girl and a boy), and in Sekai-ichi Hatsukoi are two adult men.
But, all in all, if u like romance (in all variants), good voice actors, and interesting (in rolling-on-the-floor-and-laughing kind of way) facial expressions and characters reaction, then these are animes for u!
