I'm pretty sure it's a manhwa, and I forgot the details. But there's this one situation where a guy liked his friend I think, so when his friend told him that he was going to a military school (or probably serve his military time?? Not sure) but then when the mc got in, he called his friend to ask where he is, but he just said that he changed his mind.
Such a situation happens in a flashback to the the 2nd couple in "Fallen Star." There are 2 couples who know each other so the webtoon is not divided, their stories are intertwined. Not sure if it's what you're searching for since it's just one scene you described and that webtoon is not on mangago (I've read it on webcomics) but it definitely has such a situation...
Manga about a guy who ran away because he was going to be in an arranged marriage and he met someone on the train. I forgot what happened, but the guy he met while on the run was related to the family he was supposed to marry.
I've read this as well, and have tried searching for it now without success. Wasn't there a scene outside the building where he works, where he meets the guy for the second time (ie, after the train meeting), and that's when he finds out that the guy on the train is a part of the family he's supposed to join, or something?
Is it this? If it is, then it's just a single chapter/one-shot in a collection.

Manga about a hot guy (seme) and was perfect at everything (even school). But he worked hard for it and a guy (uke) said something that made him misunderstand. I forgot what happened but the seme offered this guy a tutorial and he was wondering why he can resist his charms. It turned out that the uke's family was charming and the uke was used to it.
It's a side story, but it's about a host with a neighbor that's a doctor. He's living in a beat up apartment because he only goes there to sleep, so it doesn't matter. Somehow he's attracted to his neighbor and one suddenly he smelt gas from his apartment so he saved the doctor. When the got together they moved to another apartment and since the host was rich, he built the doctor a clinic next to his convenience store, and he stopped working at the host club.

Full color webtoon that's basically porn. I didn't read it properly so I'm not sure but I think his friend offered him a job and there's this party in a pool??? I can't remember ( ̄∇ ̄")
