Since I'm not familiar with 'patience kys', it could be that it was created randomly by someone in a chat room or a social media platform. Maybe it was a moment of frustration where they combined 'patience' with something else in a rather unorthodox way. But again, this is just speculation without more information about its context.
Sure is! Frieren has a dedicated fan base thanks to its engaging plot and well-developed characters. The manga has attracted a lot of attention in the comic world.
The term 'patience kys' is rather unclear. It could potentially be a play on words or a very specific in - joke in a certain context. For example, if it's related to a new meme or trend, the origin might be traced back to the person or group who first started using it in that way. But as it stands, without more details, we can't accurately determine its origin story.
