Help Realizing Which Anime I’m Thinking Of

[drizzleRomanceGirl]

will someone please help me realize which anime i’m thinking of? i only watched the very beginning of the anime i think but in the beginning of the anime two boys from the student council are talking and one person says that for his original personality he used to be really impulsive and hot-headed but he changed his personality so he’s more calm and collected - i think it’s because he’s either part of the student council or he got older

also i think they’re in middle school but i’m not sure at all so i could be wrong and i’m pretty sure the anime was released in the 2000s but i’m not completely sure
