I was pulled into the story the moment I watched the trailers for this drama and it sure did not disappoint. It is a great time-traveling romance and suspense story that is brilliantly told. I went in thinking I knew what would happen but the story turned out quite different than I expected so don't go into the story with any judgment. The actors did an amazing job at bringing their characters to life and the soundtracks helped complete the story. They cast great actors for Wan Sen and Bei Xing because they were able to make the story touching but not pushy. There are definitely many drama cliches in this drama but they were used in a way that breaks your heart and makes you feel for the characters, Zhang Wan Sen and Lin Bei Xing. The romance between Wan Sen and Bei Xing is also written so beautifully tragic, which makes you can't help but keep watching them because you want a romance like that. You won't be able to stop yourself from hurting for Wan Sen and Bei Xing. Also, the script was written consistently despite the time-traveling element so there were no plot holes. The details of the main storyline did not change and you start to notice the smaller details. I totally fell in love with Wan Sen after watching this drama and now I feel empty and sad. There are certainly angsty moments in this drama and I cried a lot, but it is all worth it. The love story is an emotional journey that was worth watching how it unfolded. I would say enjoy the first half because the second half will break your heart. It hurts that a Wan Sen doesn't exist in real life. T_T But just enjoy the drama when you're watching because you'll be so sad when it's over. An "I like you" never hurt this bad. ALSO this drama is NOT DUBBED so all of the actors are using their real voices which is such a great thing because I hate it when a drama has a dubber who does not match the actor. So, I TOTALLY RECOMMEND this drama if you like time traveling and a cute romance! Once you fall into this drama, you won't be able to get out.

Now, some points that I really liked and didn't like:

Things I liked:
1. The cinematography- All of the scenes were filmed in a way to add emotions to what was going on. It makes the scene more tragic or happy. I couldn't help but screenshot some moments because it was filmed so nicely.
2. The acting!! - I have to compliment the actors who played Wan Sen and Bei Xing for their incredible job at playing the role. Wan Sen was so adorable and timid, which was only possible because Qu Chu Xiao did such a great job at embodying the character. Karlina Zhang was also just as amazing at playing Bei Xing and doing the emotional scenes so well. I can't imagine anyone else playing these roles because no one could have done it better.
3. the romance - Wan Sen and Bei Xing are so cute together. They are a cute dynamic that was fun to watch with cute scenes that were not too cheesy. My heart always fluttered watching Wan Sen be completely in love with Bei Xing and happy to do anything with her. Wan Sen's smile was so cute to watch. It's such a shame that Bei Xing took so long to notice him.
4. the music - the soundtracks were absolutely amazing! They all had lyrics that pertained to the story and characters. Noteably, the song titled "The World is Behind You" and "The World is Behind Me" and "Goodbye" were so heartbreaking to listen to. The first two of those songs were sung in different perspectives; one from Bei Xing and one from Wan Sen. When you listen to the lyrics, it'll make you feel even sadder for the characters if you weren't already. I have been playing these three songs on repeat because it just hurts so much.
5. Styling- I also liked how Wan Sen and Bei Xing always had different outfits when they were not wearing their school uniforms. This is the first time I have seen a drama do that which is nice to see. The outfits made Wan Sen more adorable.

Things I didn't like so much:
1. Supporting romance line- the romance between Gao Ge and Cao Yang was a bit boring and unrelated to the main storyline. so I skipped some of their scenes sometimes
2. Open ending- I wish that the drama could have ended with showing Wan Sen and Bei Xing meeting again and having some interactions because it ended so sadly.
