• Excerpts released online express affection for an unnamed partner, which the lawyer argues reflect contemporaneous thoughts and constitute credible evidence.
• Ko says only one letter went to Kim Sae-ron in June 2018 and that its tone resembled friendly correspondence, noting a same-day diary entry about missing his actual partner.
• The defense cites a postcard from November 2019 and photos dated December 2019 to January 2020 to argue the relationship with Kim Sae-ron began after she became an adult.
• Kim Soo-hyun has acknowledged dating Kim Sae-ron in 2019–2020, while both sides pursue defamation and related claims after a separate recording was challenged as fabricated.
