Actor Kim Eui-sung and actress Han Hyo-joo, who played father and daughter in MBC‘s fantasy series “W,” were reunited at the 21st Busan International Film Festival which kicked off Thursday.

Kim posted a playful photo of Han and himself with veteran actor Sul Kyung-gu on his Instagram account Friday morning.

“Oh my daughter!” he wrote on the post.

Kim played a Webtoonist while Han played his daughter, both of whom get sucked into the world of "W," created by the artist.

The BIFF 2016 will run until Oct. 15.
