CN Blue's Kang Min Hyuk Likes Krystal's Photo on Instagram. Publicly Flirting?

Fans have been shipping the former 'The Heirs' co-stars after the boybander liked the f(x) member's new photo.

Krystal recently took to her Instagram page to share a new photo of herself during her trip to Singapore. The f(x) member looked pretty with her new short haircut despite her pose, which suggested that she was moody in the image.

Wearing a pair of oversized specs, she gazed longingly in the picture while sitting on a round table. She appeared to be ready for a lunch or dinner as a dining set, including two glasses and a plate, already set on the table.

But it's not Krystal's pose or her beauty that got people talking on the Internet. Apparently also amazed by her beauty in the picture, Kang Min Hyuk, her co-star on 2013's "The Heirs", liked the post and this has sent people into frenzy.

Fans who noticed Min Hyuk's activity on the social media site have since teased the two. "Aw aw aw @mr_kanggun," one wrote. One fan pointed out, "Minhyuk liked your pic." Another similarly wrote, @mr_kanggun like this.."

"chanyeong bona couple @mr_kanggun @vousmevoyez," another commented, referring to their characters on the SBS teen drama. Another was shipping the twosome, "Couple of the year @mr_kanggun @vousmevoyez."

Min Hyuk had previously expressed his admiration for the "My Lovely Girl" actress. On a recording for the broadcast of "Video Star" in July, the CN Blue member revealed that Krystal was his favorite female co-star.

"Out of the actresses that I worked with, I liked Krystal the most," he admitted. He explained, "She was really like a little sister, and she was so cute." The 26-year-old singer/songwriter/actor is currently starring opposite Ha Ji Won on MBC's medical drama "Hospital Ship" and has worked with Park Shin Hye, Moon Chae Won and Oh Yeon Seo among others.

Krystal is currently single after splitting from EXO's Kai. SM Entertainment confirmed in May this year that the two broke up after approximately a year together. It was reported that they grew distant because of their busy schedules.
