The two have been in a relationship for a long time.

In a handwritten letter posted to Instagram, Song said he had "promised marriage to the person I want to spend my life with."

"I have found someone with whom I feel most like myself — at ease and happy — and with whom I want to share that happiness fully." He added that the two were "tying the knot so we can be each other's greatest supporters, side by side, for the rest of our lives."

Song also pledged to "work hard to become a better person and a better actor, and to live well."

Song made his debut in the 2013 film "Friend: The Great Legacy" and went on to play Im-geum, the oppa of Im Sol (played by Kim Hye-yun), in "Lovely Runner," and Seo Jeong-min, the son of Cha Jeong-suk (Uhm Jung-hwa) and Seo In-ho (Kim Byung-chul), in "Doctor Cha." He also appeared in "To My Beloved Thief," which wrapped in February.

Kim So-ri, the bride-to-be, made her debut as a singer in 2016 and has been active as a member of the group Real Girl Project (R.G.P). She has also appeared on the variety show "Somebody 2," the drama series "The Idolmaster KR," and the survival program "Mix Nine."
