Yoo In Na's agency YG Entertainment rep told Newsen on the 18th, "Yoo In Na is positively reviewing the casting offer for 'Wedding Bible'. But there are still negotiations to work out so it is too early to say that it's confirmed."
Ahn Jae Hyun's agency HB Entertainment rep also stated, "Ahn Jae Hyun will star in 'Wedding Bible'... It has recently been decided and we haven't been able to confirm the film synopsis and character details yet. He is set to enter filming in July."
'Wedding Bible' is a romantic comedy film which portrays the love story of a Chinese and Korean couple. If they're both confirmed, Yoo In Na and Ahn Jae Hyun will act alongside Jiajia Deng and Godfrey Gao.
