International fan here:
I don't usually watch Cdrama, but this one piqued my interest. The story is based on a novel titled: "secretly secretly but unable to hide it" by zhu yi. I read some chapters and love that the series made sure it sticks closely to the original source. I love how the story unfolded. It guides the audience on how the relationship started from platonic to puppy love and finally true love. It clearly showed the transition of the guy's feelings from an overly protective older brother to something more. The story tells us about how someone can be one's destiny. Sang Zhi was exactly what Duan Jia Xu needed at the right moments and times. She was the little sister when he needed one. She was like a best friend when he needed someone to share his secret, and the girlfriend who loved him as who he was and will be.
I am a fan of the main and secondary leads acting. Their facial expression is convincing. The dialogues are also very witty and entertaining. I really love this drama and would highly recommend this. It is funny and touching. The sweet parts can also give you diabetes. Hahaha!
Congratulations to the team and crew!
