Kim Soo Hyun was embroiled in a dispute with the family of the late Kim Sae Ron, who passed away in February. The family demanded that Kim Soo Hyun acknowledge his romantic relationship with the deceased and publicly apologize. Despite fans' urging to unfollow Kim Soo Hyun, Jung Hae In has stayed silent on the matter. This has led to mixed reactions from netizens, with some defending Jung Hae In's decision to maintain his friendship with Kim Soo Hyun as a personal matter, while others advised him to unfollow for his own benefit. Another cast member of 'Good Day,' Jo Se Ho, was also speculated about unfollowing Kim Soo Hyun, which he clarified was not the case. Kim Soo Hyun, on March 31, announced that he had filed a lawsuit against the bereaved family of Kim Sae Ron and other individuals involved in the controversy, seeking damages of approximately 12 billion KRW.
