I'm trying to find this BL. So the setting was something like this. It was a kinda dystopian world. South Korea was divided into multiple circular zones/rings. The core was the most prosperous and resourceful zone. As you move out from the core the conditions get worse and worse. It was said that the core zone acts as the Sun and the other zones revolve around it like planets.
MC was from one of the outer zones and he wanted to move to one of the safer zones.

A person was searching for it and I found it interesting. I hope someone will know it.
I have been searching for this Chinese bl novel I have read a while back, it talks about a cultivator that travels in time to the faraway future where women do not exist, only men and ger (like omegas, men who can give birth). In the future, he is this jobless man who got kicked out of his job (he was a teacher) and his partner broke up with him. In this world humans have long since left earth, and conquered planets, women gradually disappeared and the human body changed to support its survival. Fast forward, mc finds himself in a system which (from the og owner's body) he doesn't remember signing up to, said system paired up people based on their compatibility. And so mc was matched was Mor (I'm not sure about the name), this very stoic, powerful ger son of the (I forgot the rank but but yeah, his father is a powerful military leader). Blah blah blah, stuff happens, MC accompanies Mor top planet Earth which is now covered in this dark purple hue making it impossible to discover, most of the team gets killed and they're attacked by some sort of dark wolves and MC has to use his powers to save Mor. (From then they start to like each other). Mc loses all his cultivation and has to cultivate it back again when he goes to the future. They have a kid together and MC is forced back to return to the past.. I'm begging all of you, does this sound familiar!? Please!!

I don't know if this is the one you're looking for:

What is the difference between a Sociopath and a Psychopath? Like I thought its synonyms and I used it interchangeably. I searched on the Internet but it just said that the terms aren't used in clinical treatment and the difference isn't much. But it said that Psychopaths are calculative and don't feel any guilt and on the other hand, sociopaths are erratic and they may feel guilt.
I would appreciate it if you could explain it with the help of characters from manga/manhwa/anime or even from movies.

In this story the ML is a diagnosed psychopath and the link I provided show screenshots form the author’s twitter. If you scroll down to about the middle of the screenshots she breaks down the whole psycho/sociopath.
You’re right, those terms aren’t used in the medidos field anymore, I think now they use terms like borderline personality disorder and other terms like that.
But anyway, hopefully this can help you answer your question.
