TLDR: More of a 8/10 stars tbh, overhyped by the reviews. First 4-5 episodes are boring, story gets interesting afterwards but timeline gets increasingly confusing as the drama continues on. Even by the end it's not 100% clear and you're left unsatisfied because there's so much jumping bodies.

The ending made me kind of annoyed because it made the entire drama redundant, I might as well have not watched it, the ending was useless lol. I think a one-time watch is enough for this if you're into time travel, but personally I won't rewatching.

I absolutely loved discovering Greg Hsu however, super handsome and cute and has such a great smile. I loved his couple scenes with Huang Yu Xuan, so cute. I'll look forward to his new works!
