not sure abt the other details but here's the only manhua that I could think of

the only basis of this is the "chinese" part and company setting. I don't remember that much abt its plot but I do remember that he was able to get the job bc he cross-dressed (I think he was kinda forced to do so)
Thanks for the update but this is not the one. I’m not really sure if the manhwa I’m talking about was in a company setting or university/ school one I read it years back
I read a webtoon ages back ( pretty sure it was Chinese) and the uke pretended to a girl to get a job? And the seme from the beginning interacted with uke and cross-dressed uke and thought that uke had a sister? So not sure if this was a school/ university setting or company setting? But I remember this one chanter where seme saw uke’s real hair peaking out of his wig while uke was unconscious on a couch. And further down seme discovers that uke is a boy and boom there’s drama and uke thinks that seme hates but seme is just conflicted?
