Kissed Him and Ran: The Cannon-Fodder Role Turns into a Sweet Romance

The true and false young masters: The male lead is the real young master, but he himself is currently unaware of this. Knowing this background, the female lead goes to the fake young master's company and becomes his assistant (she also learns later that the fake young master has feelings for her). Despite the male lead's extreme insecurity (his current financial situation is not as good as the fake young master's wealth), he still doesn't avoid suspicion. Furthermore, after the fake young master tentatively used her as a bargaining chip in a business deal and was sexually assaulted in the restroom (even though he knew she didn't want to stop and take her away), he was still able to continue working for him as if nothing had happened. To repay the female lead's online loan, she borrowed money from her toxic best friend without the male lead knowing. The best friend then used this opportunity to blackmail her into meeting her online boyfriend in person, since the friend had used her photo... The female lead agreed. The online boyfriend was very satisfied with her in person, but her toxic best friend continued to threaten her, saying she would contact her again if she didn't agree, and that she would tell the female protagonist's parents about her current impoverished situation?! The female protagonist agreed!!! She accompanies the fake young master to a lavish banquet attended by powerful figures, where she encounters her best friend's online boyfriend... He tells the fake young master, who is also the female lead's boss, that she is his girlfriend. (The fake young master knows she has a boyfriend and has met him, so he assumes she's two-timing and warns her not to hurt her online boyfriend or things will get out of hand.) The female lead, however, thinks no one will believe her anyway, so she simply doesn't explain... Her thought process is absolutely phenomenal!
