Protect the Boss (ABS-CBN)

The story depicts on Cha Ji-heon  which is an extremely immature young man who is useless at his job as a director at DN Group, where the chairman is his father. Ji-heon has a old rival in work and love with cousin Cha Mu-won, as Mu-won is a mature, hardworking, and perfect executive, and the two both have a romantic history with Seo Na-yoon . Energetic and tough Noh Eun-seol  is struggling to find full-time work because of her childish bad  record and poor academic background. After giving the hiring directors a piece of her mind during a job interview at DN Group, she is surprised to find herself hired by Mu-won (who was captivated by her interview) to be the secretary to Ji-heon. Determined not to be fired from her first professional job, Eun-seol works diligently at putting up with Ji-heon's childishness and keeping him in check. As their working relationship progresses, they earn each others' trust and friendship, and Eun-seol helps Ji-heon deal with his phobias and prove himself capable of becoming DN Group's successor. Things get more complicated when Ji-heon and Mu-won both fall for Eun-seol, who doesn't want to get mixed up with either of them.
