looking for a manhwa where the main character's job involves testing the fidelity of people's partners. She eventually meets a man at a bar, initially mistaking him for her target, and they start dating. There's also a subplot involving her boyfriend's friends, one of whom is an author, and another is cheating on his wife within their friend group.

If I remember in the beginning this highschool boy works for an organization that defeats aliens. And there is another boy that got on a train and got taken by an alien grandma. I remember the boy that got kidnap did also find out his dead dad worked for the alien organization that the other boy works at.

It was about a person who went to hell to become a teacher. He doesn't't know how he got there and he had like some dark past. I think he is keeping it a secret that he is human. Thanks!

I'm not exactly sure, but perhaps this is what you're looking for?
I can't remember much. All I remember that the mc was like a training priest, and he was really good at playing this one instrument during mass. He was told that he put to much emotion in it or something. Thanks
Found it. Ice lamp.
