Interesting casting news as Fu Xin Bo and Ying Er are not unfamiliar. They are a couple on a Chinese dating show called Perhaps Love (如果爱) that started airing a month ago with 3 total couples in collaboration with Korean company CJ E&M. Legend of the Ancient Sword (Gu Jian Qi Tan) Season 2 will not be a sequel but a new story. Production will begin clicking soon! More info will come out then.
They look cute on their show. Must be nice to be familiar before starting a drama together.
