Anime about high school club members helping other students. What was the title?

It was about a group of three high schoolers ( an introverted slacker guy, Introverted girl with long black hair (the leader) and a joyful girl with shorter pink or orange hair) that were members of a weird club- they were getting requests for help from other students and they were trying to help them. 
It's been a long time since I stopped watching anime but I just rememnered random scenes from one of them and got annoyed because I can't recall the title. Help? :(

@Eliza YES! Thank you very much.
