Good drama for action thriller seekers

Good story line. Jiwoo (female lead) has done great character work. The antagonist(Choi Mujin) character was also strong. the only issue I felt was the forced love angle between Jiwoo and Pildo which was not necessary at all. They could have shown more attachment if they wanted us to connect to their chemistry or they could have just let them be best friends at work or something rather than dragging it. also there was no need to kill Pildo at the end.. and last scene, Jiwoo was content which is not right. dint like the ending. but overall good drama
