Her fiancé, Park Jung-jin, shared a video on his Instagram on the 20th with the simple caption, "Will you marry me?"
The video reveals Park Jung-jin's surprise proposal for Song Sera. Believing it to be a small event, Song Sera entered the yacht unsuspectingly, only to be amazed by the pink-themed proposal message.
Friends of the couple appeared one by one, each presenting a rose to Song Sera, who responded with tears of joy.
Park Jung-jin then knelt before Song Sera, offering her a ring. She removed the ring from her ring finger and accepted the new one.
The couple met on the show 'Love Catcher 2' and are set to tie the knot this spring. Park Jung-jin had previously proposed in Shanghai, China, last November.
In August of last year, they announced their engagement on their YouTube channel 'Sera and Jung-jin.' They explained, "We weren't planning on having children, but if we do, we need to register the birth and get married, so it naturally led to marriage."
Park Jung-jin was born in 1991, and Song Sera in 1993.
