I missed half of episode 7 on Monday but will re-watch its repeat this weekend.
Episode 7 is where Mu Yeom was hit by a bullet from Chul Gon’s gun when he was playing Russian roulette with psycho Ryu Tae Oh. As it was too risky to remove the bullet from his head, Mu Yeom would occasionally suffer intense headaches.
As Mu Yeom goes through the past murder cases, he feels a deep sadness for the helpless victims.
Even as he feels relieved that Ma Ji-eul is safe, he’s furious with her for not heeding his advice to stay away from Tae Oh.
Filled with remorse that he was unable to stop the murder of the 5th victim in the nursery
Vowing to get Tae Oh.
Another instance of great acting in this scene.
