Honestly, this drama is amazing. I really love the actors acting and how there are so many plot twists!. There are 3 season’s but i recommend watching all 3 season’s because this drama is amazing!. If i had to say which actor did the best acting it was joo dan tae/Um Ki-joon his acting was really good. People always say if someone annoys you in a drama they were in then they good at acting. That’s what i mean by his acting is really good. I like all the actors acting though its like as if its happening in real life and not just in a drama. If you are looking for a drama with plot twists and great acting then watch this drama its an amazing drama and i 100% recommend it.
