It's not really a triangle. She loves the first lead , who loves her back and is friends with second lead (who is in love with her, but it's one sided). It has a cliffhanger ending, not really happy (at least not for all the characters or so it seems).
At the end, when pi talks about the soul, he said that if you copy a human mind into computer it will not occupy any space, but it's there. I think he said that because he did transfer Mama's mind into his servers, that's why at the end he said she could cry and that they are not divided by the screen anymore.
I've seen lots of sci-fi dramas and this is one of the best so far. Unfortunately Asian sci-fi series are usually mediocre, especially ones about AI robots that are basically just there for romance. This drama learned from novels and shows/movies like LOST, Resident Evil, Walking Dead, Maze Runner, Humans ect, so it may be not the most original show, but it still has something to offer in terms of sci-fi, horror, psychology, thriller and romance. I will recommend it even to my friends who usually don't watch Asian shows.
Yeah, it got me wondering as well. I noticed that his brother has a crush on Dan Oh (at least i think so), but…
I hope they won't do the reincarnation like story. They're kind of mainstream rn. I wish for something different. Maybe Haru or Fairy loved Dan Oh in the shadows in Flower comic, but the author made one of their characters kill her by stabbing her in the heart with a sword and that's why she feels the hearth ache in this comic(??). Something more tragic +___+
this theory create another drama, i don't think it fit here , my theory danoh and haru was in another webtoon…
That's basically what everyone already figured out, more or less. I didn't want to repeat the same deduction I and others already posted in comments below this time, but to add a new, less obvious one. Sure it may not fit this drama, like I said at the beginning, but I'm already bored ...so I imagine stuff XD
