That's like a mixture of https://www.mangago.zone/genre/School%20Life/ and https://www.mangago.zone/read-manga/love_is_an_illusion/
Oops wrong link for the first one, https://www.mangago.zone/read-manga/love_shuttle/
something like that happened here but im not sure if its this. https://www.mangago.zone/read-manga/oblivious_mr_b/
I only read the first chapter of it so I can't describe it any further, but the scene is they're co-workers then there's this omega (who I assume is pretending as an alpha) who is in heat while he's still in his work, he's the only one left in the office then the Alpha male came back and seen him in heat then helped him.
I think they do not have a good relationship with each other. They're both wearing formal suits in work, I don't know how to explain the scene more
