No there are a lot of other guides. But the Shinje doesn't match well with any other guide besides yugeon. So yugeon becomes the private guide for the Shinje and his team. His team includes heesu, taein and Yoon chan.
Question please and it's okey for spoiler too, I only read a little and saw some scenes, so is the uke or yugeon the only guide that's alive that's why everyone can use him or he is something special??
Because it seems like everyone crazy for him the way I see it.
