First thing to understand: there's an "official" edited version where they have cut out anything remotely BL--so any dialogue that had any BL feels, any scenes where they are too close/intimate--that's been cut. SO, PLEASE, WATCH THE UNEDITED VERSION.
The unedited version gave us a lot to show their love, especially Zhao Yao Hua towards Liu Yu Sheng. Again, they never do anything explicit due to censorship, but I guarantee you that this series will give you a lot to be happy and smiling about. Also, the ending is good too. So, while watching the series, don't expect anything explicit, but do expect many dialogue that will tug at your heart as well as many actions done by Yao Hua to Yu Sheng that will grip your heart. :')

Also, the secondary characters (the other couple, pretty much) also get a couple chances to shine, so that was adorable. They don't get anything as intense as Yao Hua & Yu Sheng, but it was still cute.
