In the evening of January 18, HyunA and Yong Jun-hyung updated their Instagram with the same photo at the same time.
The photo was of the two walking on the beach holding hands together, taken from the back.
Along with the photo, HyunA captioned a 'couple with a heart in the middle' emoji.
Seeing this, a lot of people started assuming that they were in a relationship, and their dating news quickly spread online.

Both of their responses were brief; they stated, "We are not involved in our artists' personal matters. So, there's nothing we can say about the news."
Since this is generally the move that entertainment agencies tend to make when something is true, it is currently believed that they are in a relationship.

Yong Jun-hyung was part of the Burning Sun scandal, where a group of K-pop stars were accused of filming sexual videos without consent and sharing them in their group chat.
Yong Jun-hyung, soloist Jung Joon-young, boy band FTISLAND's former member Choi Jong-hoon and more were the members of the group chat; they were connected to Burning Sun, which was a club owned by boy group BIGBANG's former member SEUNGRI.
The key members of the group chat, Jung Joon-young was jailed for rape and recording/sharing videos of his sexual acts with women, and Choi Jong-hoon was also sent to prison for rape.
When the police became aware of the incident and more details began to be revealed through the investigation, Yong Jun-hyung admitted to watching these illegal videos that were shared in the group chat.
Yong Jun-hyung departed from his group Highlight after that, in March 2019, and made a solo comeback in November 2022.
