Now I am 90% sure that Cha Do Won is the serial killer. Because I think only someone closed by Han Jae Hee's brother would have known that he has found some links. And Cha Do Won who could be a fellow prosecutor ticks me off.
i don't exactly remember the episode number. But apparently Choi Tae Gook is providing him with the money to fill up the hospital expenses. This is why he is loyal to him and is even ready to do the dirty work for him.
So the second half will have us looking forward to many things. 1. Park Soo Young's case 2. Gong Chan's case 3. The mystery behind Kang Eun Seo, Yoon Se Pil & Baek Jin Ki 4. Oh Soo Jae's daughter and her revenge 5. Choi Yoon Sang probably turning bad due to jealousy 6. The end of Choi Tae Gook, Han Seong Beom & Lee In Soo 7. Romance development between Oh Soo Jae & Gong Chan
