The first reason why I want to watch this drama is because I love Emma Wu and her acting since I was young. This drama has an interesting plot. There will be some repeated acts and a bit unecessary scenes that make the story longer, but overall I love the love & hate relationship between main leads.
I love how Ren Hao Ming shown as a domineering and overbearing CEO. He is a tsundere guy, that can be so damn rude and very controlling, impulsive & dominant guy, with a lonely heart. Tian tian is a cute, kind & naive. She love to bickering and she is too unstable about her own emotions, that's why she often create misunderstanding.

The title of this drama is actually more describing about Xiao xiao, the main lead's deseased sister, who also become the beginning of all the trouble between the main leads. I don't see the title is quite relevant for the main leads.

Anyway.. this drama is quite addicting, and I remember that I have re-watch it for 3x. Love the chemistry between the main leads. The ost or music of this drama are good enough.

I will recommend this drama if you are looking for a hot & possesive guy that being too obsessed with his girl. But it's kinda reasonable since he lose his sister and find Tian Tian as her replacement at first, that later on make him learn about love.

There are some critics about this drama, and here I will share my own opinions:
(1) They cut so many intimate scenes (probably it's too affectionate or contain sexual harrassment). Because of some cuts, it's a bit confusing & jumping in some scenes.
(2) They are dubbing all the actors voices. The actors acting are great, and it will be greater if they can express it using their own voices. Too bad it's being dubbed.
(3) Bad choices of wardrobe. Too many repeated or similar wardrobe that being wore by actors, especially main leads. And sometimes, they didn't change their clothes at all. The guy is so damn rich, how come he only has several clothes. And you can see the male lead has bad taste in choosing his clothes, since some looks not elegant & too colorful.
Besides, it's a republican era.. I think the clothes are too modern for some scenes, especially for female lead.
(4) It's an open ending. I wish they will make the continuation for the story, because the ending is a bit ambigous, but seems like there is no chances to see another season since they make another version with different leads.
