How again did Mugo become what he is? I cant comprehend how he explained it and how come the main family got to offer lunas to him?

That's how it usually goes when there's split personalities involved and I think that'll most likely be the case in this series too. It couldn't possibly be him at different stages of his life right? Because I'm pretty sure he wasn't able to grow old. I mean who knows how long he survived in that jar (was probably a few weeks at best) before he died/was reborn to become a God. Based on the flashback the silhouette looked like Jerk Mugo and it's pretty much confirmed he was the one who was confined due to his phobia of small spaces. It is a bit confusing tho: Jerk Mugo refers to them as different people in one breath, proclaims that he won't be the one getting devoured once he found out the boundaries between them were fading, while also telling Jaheon that he could talk about himself however he wants to when Jaheon told him not to talk badly about Sir Mugo...

Everybody is disappointed at Ido because of not going go the event. We all know the second life is about his goal of seperating himself to Sejin. Make Sejin not rely on him, not want him and not love him totally. True that they had physical contact and use to express some affection but this is all to relive the past timeline he was just trying not to recreate all the pain, hatred and losing someones life again. I understand this was all to make Sejin not die again. This is a slow pacing storytelling. The author might want the reader to feel all the angst. I am still liking it thou
It is even hard on us straight people too. Families even neighbors ask me multiple times when do I get married why I don't have children yet. Im missing out on having family and giving my parents grandchildren. How can I all do this when in this age its even harder to live on myself.
