As a time travel drama, I expected a lot of plot holes but the drama somehow was able to conclude all questions nicely.
The actress who played the FL was really good and gave different vibes for Yu Xuan and Yun Ru, even in the way they cry. My heart broke for Yu Xuan everytime she missed Quan Sheng and especially when she found the engagement ring.
The ML was a saint when I think about how much waiting he had done and will still do.
I felt that the second lead had the most important role since he was that one friend that Yun Ru really needed and it's through his actions that drama was able to turn itself around.
Hopefully more people will be able to watch and appreciate this drama.
