Great effort and attention to detail was taken to replicate some of the real events, in example:
1. The clips at the very beginning of E1, of
Alfonso Basterra Camporro,
Rosario Porto Ortega and
Asunta Yong Fang being interviewed about adoption, are an extremely accurate portrayal of the real interview. The exact same clothes were depicted for all three of them, and Asunta really was drinking an orange drink with a straw in the interview. The cutlery and crockery on the outdoor dining table is even exactly the same, down to the layout and the glass ashtray.
2. Asunta's bedroom at approximately 5:15 minutes in E1, is an almost exact replica of how the real 12-year-old girls room was found. Including the books on the floor as if she had been studying, the position of the cuddly dog toy, the doormat and the striped rug, the houses and cloud's wallpaper, the same pattern on the chair, and the green boxes under the desk.
3. Porto and Basterra really did take selfies with their daughters coffin. The white coffin, the cross, and the white flowers, seen at 41:40 minutes of E1, are all accurate details of the real wake.
Additionally, much of the clothing Porto and Basterra wear in the series are lifted from real photographs or film, as-well as the locations.
