"Kap Dong" Kim Min Jung started to suspect Km Min Sang as Kap Dong.
On the 4th episode of tvN "Kap Dong" broadcast on April 26th, Oh Maria (played by Kim Min Jung) who was fixated on the whistling sounds whenever Kap Dong happened was pictured on screen.
On this day, Maria was doing a mental exam of Ha Moo Yeom (played by Yoon Sang Hyun) at the treatment center who was the prime suspect and started to act crazy going to where the whistling sounds were coming from.
At this, Maria who met Choi Shin Ga (played by Kim Min Sang) asked, "Didn't you whistle a bit ago?" At this, Choi Shin Sa said calmly, "No.'
Maria gave up and left but couldn't stop suspecting the source of the treatment facility saying, "I'm Kap Dong." Maria watched him washing his hands and thought of Kap Dong who had touched his hands before.
It'll be interesting to see whether Kim Min Sang is Kap Dong like he suspects or whether another 3rd person is Kap Dong.
