i love how SFL is not some toxic bitch but a good person.You can see how much she cares for male lead just by wanting him be happy even if its not with her.Definetly my fav sfl in any drama ever.
the problem here is not that he is a sexist towards women being in "men" fields.The problem is him treating her like shit like she is some random stranger and not his coworker he had worked so long with who helped him many times.He should belive in her but he is just jelous she would outshine him.
