Kingyo Club
The female lead is bullied and basically doesn't have any friends in school. I wouldn't describe her as "cool" but she's a normal, good girl.
The male lead helps her out. He's popular but not arrogant, he's a really nice guy. There's another guy who likes the female lead and another girl who likes the male lead as well~ so you got your love triangles too. :[i][/i]D
