Sometimes, (low production) dramas are better than you would expect them to be. And this is one example, in these 2 seasons with total of around 4h, we get action, some romance, and nice plot twists. Of course, I didn't expect much going into this, but I have thoroughly enjoyed the ML's brains and bravery, the FL's martial arts and bossiness, and of course their cute little romance which was quite understated in my opinion, but sweet.
I would recommend watching this if you've got time on your hands and would like a short break from life. The ML was quite an eye candy for me, and I really admire his portrayal of the twins in s2 of the drama as well.
