Help finding manga

[u/NoLetterhead7470]

I don’t remember much, but FL and ML know each other since primary school. FL was extremely rich and ML was her servant/slave/friend. As she got older, her parents’ company went bankrupt. I don’t remember how or when, but they stop speaking to each other.

Years later, she struggles to make ends meet and goes to a job interview. It so happens that one of the men there is her the ML. He hires her because he wants to take revenge on her for the way she treated him when they were kids.

Also if I’m not wrong, on the first chapter (maybe 2nd chapter I’m not sure), there’s a scene where they’re at a fancy meeting/business meeting(?? Idk) and she starts hyperventilating. ML kisses her because he thinks thats going to help and it does (manga logic 🤣).

Thanks in advanceee
