I'm just broke's Manga

I thought It was going to say "Get the hell out of here" on the latest updates

I wouldn't say this is bad, bad

I don't know how to describe this actually.
So- basically Monsters. They come out of nowhere, protectors come and safety is ensured, also called. 'Sretus' or smth. Anyway, very strong student betrays academy that creates protectors and leaves world in vain. Many city's and now filles with monsters, MC gets hit by a huge piece of a building on the side of his head. Side effect? He has no emotions. He travels with his mom to find thing that can bring him and his mom back in time. Conflict ensues and MC is the only one who can go back in time, but he doesn't go back as a kid, but with his body he originally had before being teleported. He's in the academy. And so on and so forth

I don't really see much problem with this story to be honest. Or I'm just that dense

☆-2 My head hurts.
It's..a bit..

Ho-yeong dreams to be a professional football player but gave up due to some conflict, and even if he had multiple chances he didn't take them, until he got struck by lighting and was able to make a deal with the God of greed to go back 10 years ago with an ability

Started off pretty interesting, but as it progressed, the more I thought the story was getting a bit excessive. Or, over the top with the MC's talent. I know he wants to be a professional quickly and all but I can't cheer for him if I don't feel like he deserves it, like I feel bad he couldn't play football, but he didn't exactly earn it, in a way? Kinda? I don't know, it just feels wrong or smth. Also him saying "SIUUU" every time is like taking a gamble with my sanity. It hurts

Confused but intrigued

Three years ago, a doomsday prepper named Park Kyu, who predicted the world’s end and prepared for it in every way possible. As he expected, one day, a nuclear attack on Seoul led to a global nuclear war, resulting in an unprecedented apocalypse.

Despite everyone’s ridicule, the protagonist Park Kyu spent his entire fortune over the past three years to quietly dig out his own bunker. Was it merely a coincidence that he foresaw all these events?

I read this with no expectations other than curiosity and overall interest, just confused and idk if I'm keeping up with the story well. No complaints overall.
