Even if the only way to solve a problem or right a wrong is to go to a magical café and make a wish, please don't go about it like all the characters did. I know it's fiction but oof-

The story was confusing from the beginning to the end, despite the fact that they revealed almost everything and answered most of the questions that built up during the beginning in episode six. I watched all the characters make the messiest decisions and then immediately run to the café to fix the result of their actions, without ever knowing how the magic and wishings of it worked. Understanding that part of the appeal was the mysterious aura they maintained around the café, it still would have been engrossing for the viewers to have the world building revealed bit by bit in each episode as opposed to revealing everything in the finale. Long story short, they either needed more episodes to fully delve into the mysteries of the café, the beginnings, turmoils and eventual conclusions of all the characters and romances, or they needed better, more crisp writing that focused on the important aspects instead of giving backstories and screentime to characters who were only present, in a way, to fuel the decline of the leads.

None of the characters were especially interesting, no one could be deemed likeable, and the romance between these characters was as likeable as they were.
I wanted them to showcase a situation where the adult leads are caught at a crossroads, going through a bad phase in their relationship, a slump in their careers, that's what the summary promised! Instead, I got a mess. I didn't want to see a loving relationship but they kept pretending that everything was hunky dory, then all hell broke loose, and boy how! Thinking about how to explain their relationship is making my head hurt, it was that kind of a mess. I never got why they were a couple until they made that reveal in the finale.
The other couple was much better, and despite the lack of proper development (which is a recurring theme with everything in this series, nothing is developed or explained well until the last episode when it's all dumped on us in an information overload), they had me rooting for them. Until, of course, the reveal in the finale ruined their story as well.

The big reveal that we were seeing the same characters as their younger and older selves didn't work either, this was the only thing that became glaringly obvious as I watched and it should have been the biggest plot twist. They tried several others too, but at that point, I was too exhausted to care about some half done suspense. The cherry on top was the fact that when everything suddenly made sense, I just hated it even more. It was such a tedious process to get answers that simply made me angrier, and then just tired because of the realisation that an interesting premise had been melted beyond recognition and turned into a steaming pile of nonsense.

I'll be outright, reading this review will make it seem like this a series you need to watch to understand but even having watched it, I'm still confused. And a little nauseous because of how confused I am. And furious to the level that some of this may make no sense, but at least that's in keeping with the series. Give yourself a break and don't read too much into anything that you watch in this, and if you're as confused and angry as I am when you finish it, you know this review is here to help give you a little more clarity.
