This mess is a combination of bad writing and directing. The first time they used the disturbing kdrama romance tropes to show TY and JG motherly connection, I already knew the other aspects of the show would be that bad and it was a result of bad directing. The writers used scientific terms like quantum entanglement without really knowing what to do with it like "this term sounds cool, let's use it" to make their viewers feel genius with the unfamiliar and fancy terms used in the drama.

How I wished they have only used Alice as just a mere plot device to help explore more of the characters instead of delving too much into it because in the end, everything did not make sense.

The ending really threw everything that has happened in 15 episodes out in the garbage bin. The show itself is bad, but maybe worth a look if your only reason of watching is for the actors because they did great.
