The actor recently drew attention after liking an Instagram post featuring BLACKPINK’s Jisoo, sparking a wave of speculation online.
Jung Hae In and Jisoo previously starred together in the 2021 JTBC drama Snowdrop, where their on-screen chemistry quickly became a fan favorite. Despite it being Jisoo’s first acting role, the pair left a lasting impression, and interest in their dynamic has continued years later.
The post in question was a compilation of Jisoo’s kissing scenes from her current drama Boyfriend On Demand. After Jung Hae In’s like was spotted, fans began debating what it might mean.

Some saw it as a nostalgic nod to their past project, while others pointed out a more straightforward explanation—the post tagged Jung Hae In’s personal account, and he has previously shared that he often likes posts he’s tagged in by fans.
Still, the moment quickly reignited conversation around the duo, proving that even a small interaction can bring their chemistry back into the spotlight.

During the fan meeting, he said, “I’ll like everything if you tag me,” and when the fan meeting actually ended, he left likes on the posts of fans who tagged him during that time. It doesn’t mean much, so don’t say anything to undermine him https://t.co/rZwawuVRte pic.twitter.com/97fWb0qeOx
