This one, is not for everybody. Is for mature, selectiv people, or ones that wants to overcome the toxic relatioships, who wants to go deeper into human psychology, into the complex characters. I liked it, the acting was great. I love Gong Yoo natural acting but also the acting of his collegues. I enjoyed the slow and the time to contemplate the characters and the subtle communication, this was great. Even if all relationships are toxic, with narciccistic and psychopathic characters, it gives you the opportunity to understand the dynamics and to seek healing, love that inspire you, autenthic connection. For me all the movies inspire me to go beyond to surch the meanings of life. And I learn a lot. You will not lost your time. What I want for future kdramas... to introduce the mental education, that is total absent, to help people identify easily the toxic and the healty behavior.
