Clannad, Boku wa Tomodachi ga Sukunai Recommendations
Both have a guy and girl starting a club together that starts to grow, both clubs have more girls than guys, and they are both romantic anime
Both of these anime are focused on protagonists who have trouble making friends, therefore starting a club and making friends on the way. Both of them are packed with comedy, emotions and friendships.
Although it's much heavier in terms of emotions, both have a fun sense of humor and lovable cast of characters you'd have to be heartless not to like.
A club recruits members and friendships form.
They have differing morals though: Friendship in HaGaNaI, and life in Clannad.
(Oh, and Angel Beats would be another recommendation.)
The main protagonists on each anime have the same situation, they are considered like a delinquent and have no friends because of that. He will create a club with an another girl and some girl people will join the club during the history.
The past and the present history are connected on both anime.
