Yoon Si Yoon and Jin Se Yeon denied rumors that they were dating.

On May 16, a media outlet reported that the two 'Daegoon' co-stars were dating, and that Jin Se Yeon had even recommended Yoon Si Yoon for the part. The outlet further claimed that the pair often spent time together during filming.

However, both labels denied the reports. Yoon Si Yoon's label said, "The rumors are baseless. They've never even met outside of filming." Jin Se Yeon's label added, "It's not true at all. The two were close on set and they praised each other during the final interview, and that seems to have led to dating rumors."
