"South Africa, you guys are amazing!," KFC wrote.
"We've found the beautiful couple, and looks like we're having a #StreetwiseWedding y'all.
"We're meeting Bhut' Hector and his lovely bride Nonhlanhla. We'll keep you posted."
But the happiness didn't end there, as hundreds started offering the couple help with their wedding and honeymoon.
"I want to offer my performance at the wedding for free... I love love," tweeted popular singer-songwriter Zakes Bantwini.
"These honeymoon destinations look far. Someone needs to drive them there. We got you," tweeted South Africa's official Audi account.
"We would love to make their union even more special by offering them a two-page spread in our magazine so they can tell their beautiful love story!" tweeted DRUM magazine.
Brands including Coca-Cola, Audi, and Sony pledged gifts, and it even went as far as them being offered a free house (although whether this will come through is yet to be confirmed).
Kateka Malobola, who filmed the proposal and originally shared it on social media, revealed what happened when he shared the heartwarming moment.
"I took the video and sent it to a group that I've got on my WhatsApp to say 'check this out!' and I put it on Facebook and put it on Instagram, and then boom!" he said in a follow-up video.
Speaking to Sowetan Live, the couple said they were overwhelmed by the support.
The couple officially married in 2012, but he proposed again since he wasn't happy with the rings he bought at the time.
"I decided to come to KFC to give her a small surprise with a meal," he said.
"I don't work so I didn't have enough cash to give wife Nonhlanhla a befitting wedding/jewellery but wanted to do something small.
"Thank you South Africa. Your kindness has truly warmed us. We would have never imagined that our love story would have touched so many of you," the couple added.
The couple plan to have another ceremony — it is not known if they will be accepting the gifts.
