Actor-model Godfrey Gao was not only slated to be a groomsman at a friend's wedding but was also reportedly looking forward to a wedding of his own.

Taiwan-born Canadian Gao, 35, was planning to propose to his girlfriend Bella Su on Nov 28, his good friend Darren Jiang has revealed on social media. But Gao died just the day before, on Nov 27, after collapsing while filming a reality show in Zhejiang, China.

Jiang, a television personality, uploaded on Instagram and Weibo a 22-minute clip titled A Letter To My Brother G, along with a black-and-white photo of him and Gao in basketball apparel.

Jiang, 35, said in the video that Gao was planning a dinner on Nov 28 with both his and his girlfriend's families, with plans to propose to Su.

The Chinese-American said he was in Europe a few days before Gao's death when the latter called and asked where he was. "By now, I finally found out why all of the sudden you were checking to see my location," he said. "Because you'd like me to be a witness with you at the two families' big joint dinner, as you are ready for a new life direction."

Jiang said that he cried when he learnt of Gao's death, and booked the first available train to China to see Gao for the last time.

Gao's body was sent back from China to Taiwan on Monday (Dec 2).

Jiang said he has been fortunate to spend time with Gao and his family the past few days. "We brought you home together and will cope with all of this in new ways," he wrote. He added: "I'm so proud and privileged to call you my brother for this lifetime and next."

The video clip was set to See You Again, a song performed by American rapper Wiz Khalifa and American singer Charlie Puth. It was a tribute to Fast And Furious actor Paul Walker, who died in a traffic accident in 2013.
