I watched this drama on Viki but it is available on Youtube. Let me tell you exactly why you will consider this #1.

Graphics:
I never really changed the resolution when watching but it was always clear and bright. The clothing they wore was always beautiful especially Lan's Family clothing and when Wei Ying's. I never once was disappointing in their clothing choices, Infact if anything i watched this because of the clothes and the actors. Also had lovely lighting.

Music:
From the sound of the flute to the sound of the 9 stringed zither to the voices of Xiao Zhan's and Wang Yibo. I was always longing to hear the music. I even downloaded the song onto my phone and promised myself to learn the piano and play Wei Wuxian and Lan Zhan song.

Story and Plot:
I never once skipped any part, My eye's were always wide open. I never once yawned or felt annoyed because you can't miss any detail. It wasn't lacking in anything. Every episode had a story. Never once did it feel dragging. I wish that the drama could never end. I only had 2 things i wanted to see more of. I wanted to know Wei Yings past a little better and the ending was great but they could have shown Lan Zhan face but we all knew He called Wei ying at the end and you could see his figure in Wei Ying eyes.

Rewatch :

Since the first time i watched it. I have watched it 10 times or more in only 8 months. Usually i would never do that but i continuously come back for the BL? Bromance? Whatever you wanna call it.

When i first saw the cast and i didn't see romance i was skeptical and skipped it because i am a romantic nerd but as the saying goes "Don't judge a book by its cover". To all those people who are like me don't do it. I promise you won't regret it. Even if you dont like Boy romance or friendship it was not mostly about that. The story line had betrayal, death, rising to the top and plummeting to the bottom and lack of trust by the persons who are closest to you...
