Which of the upload here is where the kids are all grown up and Ao is in highschool where they met his crush?

Hellooo, I think you’re talking about this : https://www.mangago.zone/read-manga/kiraide_isasete/uu/to_v-4-chapter-4/pg-1/
(If it doesn’t work it’s on the end of chap4 vol4)
Enjoy ! (▰˘◡˘▰)

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...
Is the plot still plausible? Is the mc already an omega? Or did that prof already choke himself? Is this still worth reading? I stopped actually right after WJ and Prof first meeting.
