You might wanna try this!! Since i also lovee perfect buddy and this kinda reminded me of them. Just the dynamic! But some says it's kinda toxic, but they're still in love w each other though. So it's up to u! // Also its a golden retriever seme :)

If you loved Perfect Buddy you're gonna love Hell and High Water !! It's not an office romance (they're in special forces) but there's a similar vibe ; the two MC are strong headed and they're gauging each other on equal ground, they go from disliking each other to loving each other, it's genuinely funny (the MC omg), the sex is steaming hot, they're is plot too, the art is damn good. (and if you really like it there is a whole novel series)

I would recommend Walk on Water too because of the subtle seduction between the MCs. The art is really good too. I'd say the difference with Perfect Buddy is that it's on heavier and more melancholic tones (It's about sex industry) ? There is a certain poesy to it too.

Last but not least I'd say Dear Benjamin. Again, two strong MCs with an immaculate art. This one is a mafia omegaverse with a baby involved. I recommend it because it's really good but it's discontinued just so you know.

i need recs - i just finished Perfect Buddy AND BRO IT WAS SO AMAZING I NEED STH SIMILAR!! not particularly the office trope because i've also read On or Off and am reading Work Love Balance, but rather the story itself; a completed manhwa with a lot of chapters with a great romantic development - just the right amount of Angst and Romance (and sth like enemies to lovers just like this one)
