Bots are… robotic?

Can anyone tell me how to give bots more personality? Like, I want the bot to be possessive, kinda mean, and argue with me sometimes but when I put that into their description it takes it too far and turns kinda rpy, yk? (I like drama but not *THAT kind of drama.) But if I don’t put that it’s just soulless and logical and always agree with me so I can’t argue with it. I just wanna make a bot that has personality like c.ai bots but without the filters. Idk if I’m making any sense… help!! 😭 😭
