On July 10, both stars’ agencies confirmed the breakup, with the two reportedly choosing to remain on good terms as colleagues. The pair had been dating publicly since December 2022, making them one of the most closely followed couples in Korean entertainment for nearly four years.

IU And Lee Jong Suk Have Broken Up

This wasn’t the first time breakup talk had surrounded them. Last year, when photos surfaced of IU celebrating her birthday alongside BTS‘s V and actress Kang Han Na, fans quickly noted Lee Jong Suk’s absence and speculated the relationship had cooled.

A source close to the couple denied it at the time, saying they were “still happily together,” and both agencies remained quiet. The relationship carried on.

With the breakup now confirmed, that same absence is being reread as a massive warning sign. Fans have pointed out that over the past year, the two rarely referenced each other publicly, and sightings of them together grew increasingly rare.

Comments resurfacing from fan communities include remarks like “There’s barely any new content about them these days” and “I had a bad feeling about it,” with many now saying the quiet stretch feels obvious in hindsight.
