Yes both of the two leads did give justice from ther roles and it got me in EXTREME ROLLER COASTER rides, with many psychological terms or illnesses that mind blown me more than i expected. I never expected this drama to be great. But i really hate Haesoo's mom and her sister ther both btchess tskkk… but the rest all of them have perfect execution of ther roles i love it. Im about to laugh becoz almost all of people inside the ML house are all PSYCHOPATHS its so fcking hilarious i cant with this. And also ive learn many lessons from this drama it so relatable in our daily lives. I cried more than any more drama that i have watched so far so ready for your tissues if you wanna watched already. Im really of Gong Hyo Jin i love her even more in this drama.SHES LIT AS FCK !!!! Highly recommeneded!!!
