After a year, I decided to rewatch it. The foreshadowing from the ost on the first eps is insane. Also I am now 100% sure that ZWS is alive because of all the little details of hints that I miss first time I watched it.
Okay my prediction why Dr Roy likes being with Dr. Cha. I believe both know each other long ago. Dr. Roy is from an orphanage maybe Dr. Cha went there for something like a volunteer when she was young and meet Dr. Roy there. Maybe Dr. Roy knows her long ago and Dr. Cha seems to brighten his life a bit in the orphanage thats why he cares so mucb for her.
The worst ending ever. Whats the point of their struggles to survive? Ill pretend the last episode didnt exist. Ill convince my brain to erase that scene in my memory. The webtoon ending was so much better than this.
The fl acting is very off too.
PS. Im on Episode 8 so dont spoil me
