I'm a fan of detective / mystery thriller drama for both western & eastern. I watched this drama while airing via Youtube.
Detective storyline is pretty remarkable. If you like detective type of drama, you gonna like this. It's a light and simple mystery solving, not deep like popular western detective series / drama.
Settings during Chinese era (circa 1920ish) are picturesque. Your eyes gonna like it feel like nostalgic.
Bromance was all over the place. Well, it's not actually bromance on paper, it's definitely a BL.
At first, I didn't realise it would lead to BL (didn't watch any review beforehand), however you can feel ambience and your cheeks were blushing while watching the bromance scenes - finally you realize, ahh!
They just fit the bill for the role (sugar daddy role, Yi Tian's soft personality, wealthy background, etc).

My utmost disappointment (until now and forever) relies on Bai You Ning's character. Her character was poorly written with no development & meaning for overall series. She is literally like everyone's said - annoying and useless. Her start was quite normal as spoiled brat, probably could be a soft / fresh colour between two men. Later on I found out, her character didn't contribute any good, even for professional or personal til the end.
She didn't help at all in solving cases, consistently stubborn / drama queen, and just bothersome for working environment.
If you want to form a group, they must be have their own ability to help each other.
In here, Bai You Ning was nothing.

The title is also misleading. Bai You Ning & Lu Yao were indeed the roommate. However, this story was fully emphasized (before episode 30ish) about Lu Yao & Chu Seng until finally Bai You Ning & Lu Yao forcefully by story got married. They indeed had bickering and teasing all the time, but those were family bickering. You may sense the bickering wasn't like romcom bickering turned into romance. At some point, I thought Lu Yao would end their friendship because of unforgivable attention seeking events caused by Bai You Ning.
Personally I thought Bai You Ning is a cherry on top due to censorship that leaded to forcefully happy straight ending.
If they stay as team without any romance, it would be better.
Hua Yi Tian is definitely handsome (every time) but I can't get enough of Zhang Yun Long. I started to notice him and suddenly my phone is full of him. He is so damn sexy with his sleek hair, police attire and his flirty gesture.

Overall, I recommend this drama if you don't mind the ending. I don't know about others, but I mostly skip hateful part at Chinese drama. You may skip sparks between Bai You Ning & Lu Yao.
