Immortality or The Husky And His White Cat Shizun, is a live action base on a BL Novel. Sadly the drama wont be out until 2021 spring, but in the meantime you can listen to it's CD Drama and read the novel, it does have a Manhua but I haven't found any English translation or a place to read it.
If you also know and enjoyed Scum Villain Self-Saving System (another BL novel) then I would like to think you will enjoy this!
