To the person who recommended Introverted Boss, it had a revenge plot for the first like four episodes but the viewers complained about it because they thought it made the female lead unlikable so the writers scrapped the script, reshot episodes 5&6, and ended the revenge there. From episode 6 on they started building up the leads' romantic relationship.
Don't get me wrong, it's an amazing drama and the fact that she joined the company with the goal of revenge is not completely dropped, she just stops actively seeking revenge at episode four.
