I was honestly expecting so much from the drama. I haven't watched the original Taiwanese version of the drama but I saw on the reviews that it was better, so if you wanna watch this, I think it's better to watch the original version.

I had too many questions left unanswered at the end of the drama. Like what happened to the original Koo Yeon Jun's soul if both of the souls in the body belonged to Nam Si Heon? And they showed only the place where Kwon Min Ju soul hid when Han Jun Hee took over but what about Oh Chan Hee? he was the elder brother but in the past, the elder brother's body had Oh Chan Yeong's soul.

The time loop was confusing and ambiguous. I liked the direction that the story was meant to go, but I didn't like the way it was shown in the drama.

We also didn't get to see what ending Jung In Kyu and Kwon Min Ju got. I mean, if they really ended up dating, then did the two best friends end up dating doppelgangers with the same face or what?

I liked the songs and the acting , and I felt like Ahn Hyo Seop had more chemistry with Rowoon than Jeon Yeo Been. I was invested in their cameo story.
