Bishonen anime recomendations?

I love animes like - K - Pandora Hearts - No. 6 - Karneval - Kuroshitsuji - Nabari no ou I hope you've found what all of those have in common. All of them are about two cute guys, one of them is a badass and protects the other. I don't like funny ones or ones that are too cute and I definitely love action. Is there any anime who checks all of those boxes? I know it's hard that's why i'm asking for help, so thanks a lot on advance <3 I'll appreciate it very very mcuh.
