This is the 2nd mystery types of BL drama I liked so much ( Of course first is Triage ) . Honestly this series is so good . I am so happy that I have found this masterpiece . I am not going to spoil anything . My review is simple .

Acting - Top tier .
Story - Excellent .
Cinematography - Outstanding .
Music - The intro music is so good .
Visuals - Eye candy

Just watch it , no regrets . Aside from the mystery and story , the chemistry between the two male leads is fire . The tension is tensioning . You will know how good this drama is after watching just an episode .
