Karl-heinz Leopold is a 63 year old knight, one of the protagonists of the manhwa "Liebling!"

His traumatic past makes him a bit introverted and distant, but this old man has a heart of gold and a past he himself doesn't know of.

For those that know the original story, this is a universe where Sigmund was caught before he could bring havoc into everyone's lives. I am not fully sure if he is considered a dilf as he is not a father, but he is still a good looking old man. Treat him with kindness, he has been through a lot :(

In the manhwa it is not, like, directly stated if he is or bisexual, but for the sake of everyone, I made his character for everyone.
