They are PLENTY of sites that serve fast videos but unfortunately not all provides good quality video and
accurate or at least acceptable subtitles. I especially a bit particular about the HD videos and subtitles. I rather wait for HD English subbed than to watch a 360p video quality with a very bad translation.
I don't usually watch drama weekly but sometimes when I do and get addicted, I just can't wait to watch it. I guess this site that I'm gonna promote is the fastest among all. Note that I was not paid advertising this in my blog. You can say I'm just a satisfied drama fan? Maybe?
