Is there any recommendation about :

They are coworkers, The seme/uke is a boss that everybody hates because he's so uptight/strict , But the uke/seme is seeing him as nothing but cute/amazing . Everybody is wondering why is he so obsessed with the boss etc.

(it can be in other aspects too. for example teacher-student , boss-worker, yakuza-underling)

I've read a lot with that trope but somehow couldn't remember them. But this seems fit what you're looking for: https://www.mangaupdates.com/series/vf10ixw/punch-drunk-love. The uke is completely obsessed with the seme.
