TV Report broke the news of their breakup, stating that after two years, the two have decided to remain as colleagues with a sunbae-hoobae relationship.

With this report, Yoo In Na's agency YG Entertainment rep confirmed the breakup to several media outlets, saying, "It is true that Yoo In Na and Ji Hyun Woo broke up. The date and reason [for their breakup] involves their personal business so we do not know the exact details."

After Yoo In Na's absence at Ji Hyun Woo's discharge ceremony on May 6 and Ji Hyun Woo's very ambiguous response when asked about her, many had wondered if the two had parted ways.

Their reps had denied it initially, but it seems the couple may have already been broken up at the time.
