(CNN)November 11 was meant to be the day Intan Syari married her fiancé.
But her husband-to-be, Rio Nanda Pratama, was killed in late October when Lion Air Flight 610 crashed into the sea near Jakarta, Indonesia, soon after taking off.
On Sunday, which should have been the couple's happy day, Syari went ahead and took her wedding pictures alone -- fulfilling Pratama's final wish for her to do the shoot if he ever failed to return.
"Even though I feel grief that I cannot describe, I still have to smile for you," she wrote in the caption of a series of pictures shared on Instagram. "I cannot be sad but should be strong like you always told me to be."
Syari describes Pratama, who was a doctor, in older Instagram posts as her first love.
In the photographs shared on Instagram, Syari wears a white gown they had picked out before Pratama flew to Jakarta for a seminar, Ifan Deviandri, who works with Indra Permana, the photographer who shot the pictures, told CNN.
