I'm looking for a yaoi manga I read before it was about a man working in some company.Anyway he wants to confess to this girl, but he is very nerdy so he wants to get a fashion makeover. He gets help from another man a coworker and of course he falls in love with him, and the girl turned out to be a mean person too the way he was talked about. I think there was also abother story involving one of the other male characters and the boss of the company, where they met at a bar not knowing that they were from the same company which led to a misunderstanding later on

Is it Love Seeker by Tatsukawa Kazuto?

Yes! Thanks so much I've been looking for it for a while now
