"Our Secret" The best youth drama for me. A very realistic plot that surpasses other youth Chinese drama. The chemistry between Xu Mengjie and Chen Zheyuan is really really good. You will never get tired of it. TRUST ME! :)

Our Secret Extra is an special episode of the drama including deleted scenes from drama, some bloopers and Bridal Photoshoot. There was nothing special to watch in this episode except where Ziqi proposes to sha Di.

Overall the drama was quite good. I definitely recommend you to watch this drama, and about extra episode if you want to watch this extra episode, you can watch it as you wish. I don't love Extra episode much but I don't hate it either. It's more of a so-so.
