I am not a big fan of time travel dramas but this one surprised me. Lin Bei Xing inexplicably travels back in time after breaking up with her fiancé. Thinking that this was her chance for a re-do, she jumps at the opportunity to alter her future fate so that she will end up with Zhan Yu. Coincidentally, Bei Xing was brought back into an alternate universe where a stranger dies by apparent suicide. Each instance of her time travel seems to end at this point and after subsequent visit back to the past or alternate universe, Bei Xing gets to know that stranger before his death.

Unbeknownst to Bei Xing, the stranger is a schoolmate of hers, Wan Sen, who has been in love with her for ages, but was too timid to approach her and can only look at her from afar. Bei Xing does not realize that Wan Sen has been by her side, protecting her while she was oblivious with her obsession with Zhan Yu. This drama is about letting go of the past, and you cannot change the future by spending your time wallowing in regrets. This show is bittersweet and give poignant reminders that we must live life to the fullest before it's too late.
