This is enough to warm even the wildest of hearts.
Deep in the African bush a lioness gives giant hug to the two men who saved her.
As a cub, Sirga was driven out of her pride and rescued by Valentin Gruener and Mikkel Legarth who could not stand by and watch her die.
Now the 110lb lioness has developed an incredible bond with the pair who are fighting to save her species in Botswana, southern Africa.
Sirga treats the two conservationists just like she would other lions and with their help she can now hunt for prey on her own.
She is now a beacon for hoped success of the Modisa Wildlife Project, founded in Botswana, Africa, by Mr Gruener, from Germany, and Mr Legarth, who is Danish, with the hope of saving the lion population.
Botswana is two and a half times the size of Britain and has vast areas of wilderness - but already increased farming is bringing lions and man into more and more conflict.
From a base camp in the African bush the Modisa Wildlife Project has been working with local farmers to find a way to keeps lions and man apart.
The plan is to relocate the lions which are coming into contact with farmers to one large protected area where they have enough wild prey to feed on.
As these amazing shots show Mikkel and Valentin has an incredible affinity for the lions they rescue and not just Sirga.
Their work has now been documented by photographer Nicolai Frederik Bonnin Rossen who himself got up-close-and-personal with the magnificent predators.
Mr Legarth, 30, said his bond with Sirga was just like as if she was part of his pride.
He said: 'A pride had three cubs and two were killed before Sirga was abandoned without food. It happened on our land and we could not standby and watch her die.
'We didn't want Sirga to become like other lions in captivity, constantly fed by streams of tourists. She only interacts with me and Valentin.
'She hunts her own food, taking antelopes and she will let us be near her when she eats it which is remarkable.
'Sirga doesn't mind people, but she doesn't pay them any attention. Wild lions are scared of people, the problem comes if you release a lion that is used to people in the wild, that can cause problems.
'With Sirga we want to release her to the wild eventually as a wild lion not as one that has met lots of people. That would be dangerous.'
The Modisa Wildlife Project aims at removing lions from areas where they face certain death after coming into conflict with farmers.
Mr Legarth added: 'If you release wild lions somewhere else, they will come straight back to where they were before because there is food there.
'And if you just dump a pride of lions in the middle of a new territory they will disturb the prides that are already there.
'In Botswana all lions are protected by the government - like swans being the property of the Crown in the UK. This also makes moving them a problem.
'What we have now are 10,000-hectare plots with 10 to 15 lions in fenced enclosure, they are wild lions but we do have to feed them.
'The first time you walk up to a lion all your body is telling you this is not something you should be doing.'
