I read on "Go Ahead" Wiki that in China the rating of this drama dropped when suddenly two non-blood relater brother confessed their love for Li Jianjian. There is no way that one could just judge the drama on this basis alone. Also, both the characters in the drama have their own reasons for doing so. And to understand such a thought process, one needs to be mature and has emotional intelligence.
We all can see that Ling Xiao and Li Jianjian always have something going on (crushing each other vibe) though Li Jianjian didn't realize it before. So, it's quite normal for Ling Xiao to confess his love for Li Jianjian.
About He Ziqui, his wanting to be married to Li Jianjian is more to do with staying with the family forever. He is very protective of her. And He feels only he can protect and care for her the best.
And his love for her is very brotherly and family vibe. He loves his dad Li wholeheartedly. With this thought, his confession is justified.
The story of this drama is well thought out and well written. It depicts all the emotions which one faces in normal life. And it's truly beautiful. The actors and actresses performed outstandingly for the characters they are playing. It was a roller-coaster ride of emotions. Can't help myself saying - It was truly beautiful. Every bit of the drama is worth it. All the characters are lovely, of course! except for Ling Xiao's mum. But the actress did a great job of making us hate her so much. She really did a great job of depicting an evil, selfish-centric, and difficult-to-be-with person.
Thank you, Producer, Long Ya for producing this amazing drama and screenwriters Shui Qianmo and Wang Xiongcheng for complying with this beautiful family story.
