My idea about this series: After the first episode, I thought it would be a pleasant relaxing series where we have footage from the present when something happened and we go back to the past and the story tells us what and why happened in the past and also in the present... Reality: I was more and more out of it with each subsequent episode, I was yelled at sometimes in the 6th episode, totally psycho... who is who and at what time it happened, because the times didn't fit at all, neither the characters nor the names. From a pleasant relaxing time, it changed into a brutal game with time, storylines, and characters. I devoured this series in about two days. Thank you for releasing it into the world with all the parts at once. If it were done gradually, I would probably snap or stop watching it. The casting was 100% successful. Acting skills were at the highest level. This was the Ahn Hyo Seop I had been waiting for for a very long time. Not the artificial, conceited, most stylish one like in Business Proposal, nor such a bunny as in Abyss, or in 30 but 17. He suited me better in Lovers of the Red Sky but here in A time called you, he was perfect here from the first moment to the last. I enjoyed every scene with him. Also, Kang Hoon surprised me even more after The Red Sleeve. The boys did a great job playing both student and adult roles. And Jeon Yeo Bin was also awesome. How action-packed and funny she was in Vincenzo, here she was incredibly emotional and cared about every detail of her characters. Anyone who has seen Memories of Alhambra will surely recognize Min Jin-Woong, who he played as Hyun Bin's assistant and good friend. In this series, however, he got a completely different character, actually several characters...each different, but refined. I recommend watching this series when you have enough time to watch it continuously. I had to rewatch a few things again to better understand the storyline.
