As of February 27, Seo In Guk and Jung Eunji have been caught up in 'Lovestagram' (a combination of 'love' and 'Instagram') speculation.

At midnight on the 27th, both Seo In Guk and Jung Eunji uploaded a single photo to their respective social media accounts. Some netizens pointed out that the photos were taken in a similar setting and from a similar angle, leading to speculation that the two might have been on a date. Their matching outfits—jeans, white shirts, and beige knitwear—further fueled the rumors.

Typically, when celebrities are suspected of 'Lovestagram,' they delete the posts to avoid misunderstandings. However, both posts have remained online for over 11 hours, leading to speculation that the two might be hinting at an upcoming duet release.

Seo In Guk and Jung Eunji previously gained immense popularity for their roles as Yoon Yoon Jae and Sung Shi Won in the 2012 tvN drama 'Reply 1997.' The two played a couple in the drama, and their chemistry was widely praised. They also collaborated on the OST for 'Reply 1997,' releasing 'Love Story' Part 1 and Part 2, which became major hits.

Amidst hints of a possible musical collaboration, Seo In Guk is set to star in the upcoming U+ Mobile TV drama 'Twelve,' while Jung Eunji will lead the KBS drama '24-Hour Health Club,' premiering on April 30.
