i thinik dramafever licensed it o.o
if you search the name, they have a page for it
" Love O2O", "Princess Weiyoung", "General and I" and now "Three lives three worlds" are all on dramafever... Seems like dramafever has been spending their budget on the most anticipated Chinese dramas recently, whereas viki continues to be a miser regarding Chinese dramas and only license cheap web dramas and unpopular dramas.
