All I remember is, first, I think it is the second male lead. He is ambitious and he holds a high-ranking position in a company. At the end, he got fired because he almost or he already did endanger the company because of an illegal deed he comitted due to his ambition. He has a sister (or is she the sister of the male lead (?) sorry details are fuzzy) and the sister is friends with the female lead. Next, the female lead is the typical poor but hardworking and spunky girl in dramas if i recall correctly. Also the drama is already completed and should have aired before 2020 because i remember watching it quite some time ago. And that is about all i know :') even then some details might be inaccurate but i'll be really grateful if someone can help me out haha. Thanks in advance :)
