I watched through this whole so-so drama because I liked the revenge plot but was disappointed that 55% of the show has scenes with the 2nd lead couple, 25% for the main couple, and 20% is fighting/shooting/mystery -solving stuff. I skipped through all the 2nd lead scenes. Scenes with the main couple were not romantic either until the very last episode which contain a hug, a forehead kiss, and one hidden kiss, not sure if it's a real kiss. So if you are looking for romance in this series, you will be very disappointed. No chemistry between the main leads at all.
