This is a drama that I wanted to give up in the first five minutes and every minute thereafter. Due to the actor, whom I have positive memories of from Secret Forest, I managed to get through to the second episode, but here I probably survived for ten minutes. I love s-f, love it, but I'm begging the Korean industry to abandon this genre. This drama is a nightmare that I will dream about at night as one of the greatest stupid things ever produced. The whole scene in the plane is the negation of any sense or reason.
There may be something good about this drama, but a plot nonsense where, of course, there has to be a great tragic romance regardless of whether they come from other timelines ... (not a spoiler, that's my guess based on the second episode) Okay , I just didn't see anything good about this drama, I gave it up in the first minutes of the second episode and I regret that I started watching it at all, because I have a bad taste in my mouth because of it.

As people criticize me for daring to speak badly about this drama, I will add:
The thread "you must not meet him, you must avoid him at all costs", spoken by the girl's father, who turns out to be her husband's brother ... Why confuse the situation so much? Are these telnovela heroes who fall in love with each other, discover that they are close family so they cannot make love, but at some point it turns out that she is adopted after all, so they are not really relatives ...
Because she is killed on their wedding day, is he going to develop time travel technology? To avoid her death? This 1888 thread has been used so many times since then that I yawn.

I started watching because I love sci-fi, but that doesn't mean I'm uncritical to the genre and watch everything. I like K-dramas and have been watching them for years so I was curious about the combination and it totally missed my taste. I really don't understand why I have to keep explaining to people that everyone has the right to have an opinion and express it.
I respect those who like this drama, but I also dream about them respecting those who don't like it. If nobody blames the people who give 10/10 after watching the first episode because they are delighted and nobody tells them "wait until the last episode because you may not like you" why should I watch more episodes, "because you might like like the next episode "?

Please respect the rights of others to opinions other than yours, because not everyone has the same taste and one day you may come across a drama where you will want to tell the world how much you don't like it.
