[Reincarnated as the crazed heir] season 2 ending pls explain?

Hey guys just finished catching up on reincarnated as a crazed heir, and all I can say is I'm confused asf. So were both Jang Yagak and Ma Chunso the same person or 2 different people? Were they perpetually stuck in a time loop of dying and reviving to maintain the timeline? When Yagak broke the hour glass, did the timeline reset or was his memories sent back to the past? Because I thought he was just seeing the memories of Ma Chunso but in later chapters they say he's not and everything is real, at least that's what I got from it. And the ending, was it him waking up immediately after dying or is it the same as the beginning, where time had passed when Yagak "reincarnated" but this time Ma Chunso revived with all memories intact, therefore breaking the loop and changing the timeline? If you could explain I would greatly appreciate it, thanks.
