If Floyd Mayweather can protect his unbeaten record against Manny Pacquiao, a Bulgarian man will experience a happiness he thought long-extinguished from his life.
Because, until recently, Serafim Todorov was boxing's forgotten man.
Now, as global attention focuses on the richest fight in the history of the sport, the sad story of the last boxer to defeat Mayweather -- almost two decades ago -- has come to light.
The American will pocket a substantial part of the reported $300 million purse regardless of the outcome against Pacquiao. Todorov, meanwhile, would have to wait more than 35,000 years on his current monthly pension of under $500 to earn such a fee.
But although he harbors great regrets and bitterness over the way his life has unfolded, none of it is aimed towards Mayweather.
"I congratulate Floyd because everything he achieved in his life, he achieved with hard work," Todorov, who ended a teenage Mayweather's hopes of winning gold at the 1996 Olympic Games in Atlanta, tells CNN.
"I don't envy him because he did the right thing, he worked hard for everything he achieved in his career. He deserves everything he has."
That loss on August 2, 1996 has gone down in the history books as a turning point in Mayweather's career.
A controversial decision that evening gave Todorov a 10-9 points victory, putting the Bulgarian into the featherweight division final.
Since then, there has been no looking back for Mayweather, who is undefeated over 47 professional bouts and is regularly listed among the world's wealthiest athletes. He has won titles in five weight divisions and taken home at least $25 million for each of his past 10 fights, according to Forbes.
"I'm happy with how the result went. I'm really happy because that made me strive and work hard to get to where I'm at today," Mayweather said of his Atlanta loss on Showtime's "Inside Mayweather v Pacquiao."
Yet while Mayweather's career rapidly ascended on an upward trajectory, Todorov's descended almost as dramatically in the opposite direction -- starting with his next fight.
"At the gold medal match I felt like the judges had been corrupted and were involved in some sort of scheme," Todorov says of his defeat to Thailand's Somluck Kamsing in the Olympic final.
"I had beaten my opponent countless times before with only five days of training, and after that match everything went downhill in my life."
As Mayweather credits events of the 1996 Olympics in getting him to where he is today, so too does Todorov look at his time in Atlanta as being a turning point in his own life.
"At that point all I ever wanted was to have a gold medal from the Olympic Games, which would have given me the chance to consider myself as the perfect boxer," he says.
"After I lost we had to stay in Atlanta for two more days to wait for our plane. I drowned my sorrows in alcohol and when I came back to Bulgaria, I wanted to quit boxing."
Todorov's journey to the present day has not been an easy one -- a life plagued by depression brought on by a number of broken promises and wrong decisions.
The choice he made in the immediate aftermath of his victory over Mayweather still haunts him today.
Then 27, he was taken to doping control along with his opponent when he was approached by a group of American boxing promoters.
On the verge of winning Olympic gold, and with three world amateur titles already to his name, he was offered a lucrative deal to turn professional -- but turned it down with little thought.
Todorov believed biding his time was the more sensible option, preferring to continue with his successful amateur career and hope he would soon emerge as the new Olympic champion.
Mayweather, meanwhile, signed up with the same promoters and the rest is history.
"I was 100% sure I would win the gold medal and return in Bulgaria as a champion," Todorov says.
"If I were there right now, I would tell myself to sign the contract and stay in America. If I knew that my life would go downhill from there, I would have signed the contract right away.
"I felt like I was out of luck because I turned down a great opportunity and after that I had no choice but to return to Bulgaria where my depression started," he adds. "In my opinion the best place to be a professional boxer is America, and I lost my chance."
Upon his return home, promises of extra financial support from the Bulgarian Boxing Federation following his Olympic exploits failed to materialize.
Such treatment led Todorov, struggling to support his family, to try to switch nationalities and move to Turkey, whose boxing federation prepared to offer him a larger salary to represent the nation at the 1997 world championships.
A disagreement between the two federations, however, soon brought him crashing back to square one -- the politics of boxing had stifled him once more, this time proving to be one step too far.
Todorov quit amateur boxing after refusing to represent Bulgaria and, bar a handful of professional fights arranged for some much-needed cash, his career was over by 2003.
"My life now is my family, I don't really talk to people anymore," says Todorov, whose Olympic silver medal was lost after being donated to a museum.
"I've suffered from depression countless times in my life and even now I'm depressed. I just live a mundane life with my family."
All is not lost
Beating Mayweather may not have brought with it all the fruits that Todorov might have imagined, but the 45-year-old, now living in the small Bulgarian city of Pazardzhik, is at least starting to reap some of the rewards.
"The whole world knows about me now. I feared they might have forgotten me. Before when I was still boxing people talked about me because of my titles, and now I'm famous because of Floyd," says Todorov, who has been offered the chance to set up a boxing gym bearing his name by the Black Sea.
"Floyd, I congratulate you for being undefeated and I hope you stay undefeated. I would feel really proud because I will be the only man that has ever defeated you."
