This is an exhibition match so I think the main concern here is the participant's safety. I think this kind of fight is scripted and possibly the winner will have been decided in the deal script. This is just a money-grab fight where some of the proceeds will go to charity, as stated by @OP.
In this match, DK Yoo is heavier than Manny so I am quite interested in which weight division they are fighting. Regardless of weight, I believe we can see Manny dominating this fight for the sole reason of his boxing experience.
Most likely, boxing celebrities had already found a way to still make money after retirement, Pacman has just followed the path of Mayweather, they had retired in boxing already but still want to fight for money. If this is scripted, then we know who would win already, hopefully, there's a betting odds so I would bet on DK Yoo to survive the entire rounds.
Yeah, right, they found another way to continue making money. If Mayweather attracts an audience, I'm pretty sure that Pacquiao will do better it just a matter of how they will promote the event and how wide the scope of audiences that they are targeting. It's a good start in showing what Pacquiao still got, though it's an exhibition and most of the time it's a scripted fight so we will expect who will going to win between the two.
Maybe after this, if Pacquiao succeed with exhibition type of fight then we might see known names for him.
Though unlike what Mayweather is doing, it's good for Pacquiao to face the former champ in the same sport..
