I watched this drama solely because of Ju Jihoon. I was kinda curious at first because the plot is a bit different than the romcom lovey-dovey dramas I usually watch. Tbh, the plot sounded very boring at first, but I watched it anyway. It was a pleasant surprise for me because the story revolved around the biotech company 'Blood Free', politics and prominent figures in South Korea who were affected by a terrorist attack or who were present during it. I honestly loved the cast because the acting was phenomenal. I'm not exaggerating or anything; even the side characters like the female lead's assistant were cast so well and they understood their assignment. Otherwise, I would never be interested in watching a drama like this. Also, the drama has several action scenes which were directed pretty well. But beware, this drama doesn't have any romance, but the ML and FL have a subtle platonic thing going on like friends (I wouldn't say lovers because they didn't show any scene of them being intimate toward each other). I hope there will be a season two! I wanna know how everything gets wrapped up now because the ending felt a bit rushed for me.
