I came to watch after watching Doom at your service. I had watched shopping king. Louis half and was bored so dropped it and thot Seo in Guk is so so. But in Hello Monster i saw he is amazing.
The story is pretty good and there are times i felt sad for the brothers, where people try to make decisions for others. I liked their bromance. FL was not so bad as i have read in many reviews, she came across little selfish and little dumb but she did her part well. All in all it is a good watch. It's right amount of mystery, romance, bromance, thrill till the last episode.
