This was a really enjoyable watch. Destiny stays very light-hearted and fluffy and not particularly heavy or deep most of it's run. This works really well, because the story does each of these things really well without feeling like it lacks too much substance. But then the drama surprises you in the last few eps with some genuine depth and great plot development and a very good talent at making you feel all the feels. (And booooy did I feel all the feels.) The rules of the magic system are a little bendy at times (particularly in the latter half), changing when it suits whatever is currently happening, but it all ultimately serves the story in the right ways. I particularly love the twist that the one who is fated is able to change the fate in their book if they manage to get their hands on it, as it creates a very interesting dichotomy between the role of the gods of destiny (and who/whatever is behind them), and the people whose fates are being written.

My one quibble with this drama would be the ending. Chae Kyung has the opportunity to do just this thing, and she could have written in her book that she and Ho Yoon got to be together. There's no specified rule that says she Can't do this, especially if Ba Reum can decide he doesn't need a god of destiny anymore at all, and there's no story reason for why she Wouldn't do this. So why doesn't she do it? Why does she choose to have the same heartbreak repeated endlessly throughout her life ultimately causing her (and Ho Yoon) endless pain when she had the option to simply...not do that? Full stop, that's not romantic. That's self-mutilation. Personally, if I made it into the hall of fate, got to pick up my own book, Write In It, and no one stopped me? I'm writing my happy ending and looking up at the ceiling at the same time like 'This is your own fault for not locking the door.' Of course, I'm creative enough to make up my own head cannon, and I enjoyed the rest of this drama more than enough to not let the ending ruin it for me, so I'm choosing my own fate here an now and saying they end up together and happy and creating lots and lots of ridiculous (and ridiculously entertaining) soapy dramas till their end of their dying days.

The end.

While I could see this story being expanded to 16 episodes in order to flesh out the story and world and magic system more, I don't think that would have suited this drama. Maybe expanded the ten episodes to an hour each would have worked. But this was clearly intended to be something short and simple and genuinely pleasant to watch, and it succeeded. I definitely recommend it.
