Time and space are illusions. Everything exists at the same time. But this story is about time travel. It's about the heroine who got to go back to her past. At first, she didn't know about the reason for multiple time travel. As soon as she realised, it's a tradegy. However, no matter what Lin beixing did, nothing's changed. The ending is different but the outcomes are same.

I love the way this story developed the logical but beautiful plot though it's a sci-fi. It might be typical school love story which genius quiet boy and sloppy cute girl chasing each other, but I love the friendships that Lin beixing had whenever she travel to her past. Every story is different when every character is same. I'm cheering for Lin beixing and Zhang wansen's true love.

If you love angsty love with a very light romance and cute friendship, this is for you. But if time travel is not your alley, you can pass by this drama. This is romance drama but i promise that you will drain your eyes.
