I am craving some salarymen yaoi basically. But I'm looking for a specific trope where the subordinate starts sleeping with his boss without knowing it's his boss at first. Maybe he hasn't met his new boss yet or maybe there's a mistaken identity. The best example I can think of is Ice Eagle Fire Hawk--I'm looking for more yaoi like that. I know it's a pretty specific request, but that's what is on my mind right now. I don't mind other businessmen boss/subordinate yaoi recs though, as long as the uke isn't really girly or wimpy (like in Shachou to Hisho).

Thank you!

Yome ni Konai ka and the novel Caged Slave fits the trope you are looking for.

Though this doesn't fit your trope, Renai Shinan! is one of my faves with the boss/subordinate story.

Thank you so much for the recs! 🙂 I also love Renai Shinan too.

Salaryman yaoi is one of my favorites. Where the subordinate doesn't know it's his boss, that's harder.

Kaikan Fortune is about all I know that fits.

Doushitemo Furetakunai - probably you've read this, very popular, and not exactly what you want. He doesn't know it's his supervisor when they first meet, but finds out before they start a relationship.

Here's some other boss/subordinate yaoi that I've enjoyed:
Doushiyoumo Nai Keredo
Zantei, Koibito
Akanai Tobira
Work In
Make Me Happy - first 3 chapters
Secret News - oneshot
Otona no Manaa - oneshot
