Actor Seo In-guk and Jung Eun-ji's special "signal" is exciting fans.

At midnight on the 27th, a photo was uploaded on the official accounts of Seo In-guk and Jung Eun-ji.

The two photos released caught attention as they were taken in the same space and with similar framing. In the photos, both Seo In-guk and Jung Eun-ji are smiling while holding cameras. Their outfits also matched in a "couple look" of jeans, shirts, and knits.

In particular, Seo In-guk and Jung Eun-ji also added meaningful emoticons along with the photos. Seo In-guk added a microphone and a question mark, while Jung Eun-ji added an X after the question mark and an O after the exclamation point, increasing curiosity.

Seo In-guk and Jung Eun-ji played the characters Yun Yoon-je and Sung Si-won, respectively, in the highly popular tvN drama "Reply 1997," which aired in 2012. At the time of airing, the two received considerable response as the "Yoonje-Siwon" couple from countless drama fans.

Moreover, the song "All For You," which is the OST of "Reply 1997" and was remade and sung by Seo In-guk and Jung Eun-ji, is still loved as a "legendary duet song" even after about 13 years. Both individuals, being outstanding singers, sparked fans' "over-immersion" with their exceptional vocal skills and chemistry in the drama.

In the meantime, Seo In-guk and Jung Eun-ji are gaining enthusiastic reactions from domestic and international fans as they posted meaningful photos reminiscent of a collaboration. Some netizens wished for another duet song to follow "All For You," saying, "Release a new sound source next month."

However, earlier on Seo In-guk's official YouTube channel, a notice was posted stating, "Seo In-guk's special guest's 'interlude jump' is coming back after a long time. The common point between the two is that they are both 100% pure uppercase T! Therefore, I am thinking of carrying out 'T's Counseling Center' casually. All brave ones who need T's solution, please gather together." It is presumed that the post suggests Jung Eun-ji will be the guest for the 'interlude jump' given that both Seo In-guk and Jung Eun-ji are known to be INTP.

Meanwhile, Jung Eun-ji will appear in the new KBS2 Wednesday-Thursday drama "24-Hour Health Club," which will premiere on April 30. Seo In-guk is preparing for the release of U+ mobile TV's "Twelve" and is currently in the midst of filming for the Netflix original drama "Monthly Boyfriend."
