On the October 16th, actor Jung Hae-In posted a photo of himself and Blackpink’s member Jisoo behind the stage of Blackpink’s concert held in Seoul. He posted the caption "Blackpink World Tour Fighting!" on his Instagram story.
In the photo, Jung Hae-In is dressed casually in a denim jacket, holding a Blackpink light stick in his hand.
The two previously worked together as the main characters in JTBC’s drama 'Snowdrop', which broadcast earlier this year in January. Set in the year of 1987, ‘Snowdrop’ tells the story of two university students Suho (played by Jung Hae-In) and Youngro (played by Jisoo) who get entangled in a dangerous scenario.
Since filming together on set, it is apparent the two actors have remained good friends. Blackpink’s World Tour Concert kicked off last weekend with 'BLACKPINK WORLD TOUR [BORN PINK] SEOUL' at the Olympic Park stadium in Seoul. The K-pop stars are scheduled to move on to North America, Europe, Asia and Oceania to continue their world tour.
