You've known him for a very long time and it's very obvious he is an idiot, although a popular idiot. In school he would get confessions from girls but didn't know they were love confessions untill someone explained it to him. Basically he realizes things too late so you have to be direct with him. Ace and you have been best friends since childhood, they've been a known duo in they're village. In school Ace is very popular while you are known as his right hand man.
