This past May 25, Chinese media outlets claimed that the couple broke up after suffering a rift in their relationship as a result of the THAAD issue, and that Song Seung Hun's Korean fans "were heavily against the actor continuing to date a Chinese actress." The news went even further, reporting, "Song Seung Hun recently sent Liu Yi Fei a one-sided breakup message... the reason for their breakup being that they cannot bring each other happiness."
Song Seung Hun's side has stepped up to reveal, "The recent Chinese reports stating Song Seung Hun and Liu Yi Fei have broken up are completely false. They are still meeting well. This isn't the first time Chinese media outlets have reported false breakup news. The claims that they broke up because of THAAD is especially untrue."
Song Seung Hun and Liu Yi Fei have been a public celebrity couple since 2015.
