I reincarnated in another world, but my dad's the harem protagonist

The entire world is in shambles because of the sudden disappearance of their young males. But why is this happening?  Yes, you guessed right: they are being reincarnated into other worlds! That's the conclusion that our Main Character came to. But there wouldn't be anybody stupid (or smart) enough to actually throw themselves in front of a truck... right? Content warning: drug abuse, truck abuse, sexual tension with a pig, and so much more (: Whoever gets all the references can have as much sexual tension with a pig as he/she wants (write your guesses in the comments!)
