Espers are people with heightened and supernatural abilities. Often in stories with monsters or dungeons that they have to help defeat. While very powerful, if they use too much of their powers they can rampage or basically go crazy. This is where guides come in, they are people who help regulate the mental and emotional stability of espers so that they don’t rampage. That’s the gist of it.

Here --
It's basically differentiate on how author wants to excecute story with concept guidvesere I will explain simply --
- Esper is a person who has strongest powers (like fire , telepathy, water or things control type) they are like heroes in the world of monsters like there are monsters they fight goverment organize them and to control their power or not to rampage they need a person who will give them mine peace or calamity to power.
- guide - is a person who is meant to be with esper but his destination is simple he gives sense of calmness to his esper that's his work is not let to his esper rampage,
They don't become partners eventually cuz they are also divided in hierarchical order like S-rank esper are strongest they need same rank of guide to supervise them sometimes test are made to check if they suit each other if they suite that means they campadible the strongest the esper and match the strongest guide they needs to intimate with each other give esper sense of security or power control.
Sometimes guide played the role of archive wheel for esper who is out of control so it's easier to handle him so people around them don't get injured.
mostly this guidevese getting popular for making esper a dangerous person who are crazy mostly those are semes, they needs controler so it's important for them to have his own guide.
some guidverse also follow imprinting concept so they don't have to share each other with others especially for esper who are possesive type..
Can anyone explain to me this "esper & guide trope" in BLs?
Honestly, I've read a story about it but I think the explanation was lacking. But somehow it feels sorta like Alpha, Omega and Beta for me, like they have similar concept.
I've read a story of it but forgot the manhwa name. I'm also curious about their "job", in the story I read the author was pretty vague so I couldn't really know what it was.
