Actress Go Min-si has set the rumor mill churning and fans agog by sharing a photo of herself out at night with a mystery man.

The photo, uploaded without a caption on April 24, captured the attention of her followers, leading to speculation that the man might be fellow actor Kang Ha-neul.

In the image, the man is seen sporting a classic trench coat and exuding a stylish, well-built figure.

Although his face is not clearly visible, the post prompted netizens to ask, "Is that Kang Ha-neul?" Further fueling the rumors, Go Min-si later shared another photo featuring Kang Ha-neul on the same day.

The other photo shows Kang holding Go's hand and smooching him playfully, implying that they're close friends.

The intimate move was a hot topic online, with fans flooding social media with gush and gossip about the relationship.

Go's choice of background music further heightened the mood: Lee So-ra's "Date," often associated with romance.

Despite the rumors, the context may be more professional than personal. Go Min-si and Kang Ha-neul are set to co-star in the upcoming Genie TV original drama "Tastefully Yours," premiering on May 12 at 10 p.m.

The drama follows the story of Han Beom-woo, played by Kang Ha-neul, a chaebol heir turned "recipe hunter" who aims to inherit a food conglomerate by acquiring a small restaurant.

Go Min-si portrays Mo Yeon-joo, an ambitious chef who is in charge of a one-table eatery in Jeonju.

Whether the late-night stroll signals a real-life romance or serves as a clever promotional strategy for their new drama, the speculation has kept fans intrigued and eagerly watching for updates.

Both Go Min-si and Kang Ha-neul have yet to comment on the rumors.
