7/10 is my rating. This is a 2019 South Korean drama with 40 episodes. Each episode is 30 minutes. Uhm Da-da (Bang Min-ah) decides to interact with a humanoid robot named Zero Nine/Young-goo (Yeo Jin-goo) as the ideal boyfriend. Da-da is a special effects make-up artist who has been burned by love to the extent that she feels her heart cannot take any more. Her past boyfriend, Ma Wang-jun (Hong Jong-hyan) is not sure he is done with their relationship but Uhm Da-da may be over the mercurial nature of human emotions and the stability of unwavering love may be more her style. Or is it?

Spoiler ? I liked this series at the beginning. It was fun to get insight on the life of a special effects makeup artist. I love movies around artificial intelligence as it is our immediate future. I liked the relationship between the leads and this is one where I did not feel bad, at all, for 2nd guy. The end completely spoiled it for me as I felt like evil won the day. There is a maybe moment at the end but you really cannot tell for sure who it is she sees. I like happy well wrapped up endings. This ending is neither. I feel irritated every time I see the title or images because it could have been good but was destroyed by a horrible ending.
