On September 23, Kim Yoo-jung updated her social media with the caption, “My Dearest X. Busan. BIFF,” along with several photos taken during the 30th Busan International Film Festival.

The photos captured her preparations for the red carpet, selfies in her bold navy gown, and playful moments with the cast of her upcoming TVING drama My Dearest X. Among them was a two-shot with Kim Do-hoon, where both appeared in coordinated outfits reminiscent of a couple look — instantly catching fans’ attention.

Earlier this month, Kim Yoo-jung and Kim Do-hoon became the subject of dating rumors after online posts speculated that the two had traveled together to Nha Trang, Vietnam, following the end of their drama’s filming. Some fans even pointed to their social media posts as “love-stagram” evidence.

However, Kim Yoo-jung’s agency firmly denied the speculation, clarifying: “The rumors are not true. The Nha Trang trip was not just the two of them — it was a group trip taken by the production team after filming wrapped.”

Despite the denial, the newly released photos are fueling renewed interest in the duo’s chemistry both on- and off-screen.

Kim Yoo-jung previously went viral at BIFF for her daring red carpet look: a body-hugging navy gown with bold cutouts that became one of the most talked-about fashion moments of the festival.

Her drama My Dearest X, co-starring Kim Do-hoon and Kim Young-dae, is set to premiere on November 6 via TVING.
