All of them is kinda kakapoopoo in their heads which makes it almost impossible to hate them. There's a reason why they become like that, not justifying their weird behaviors it's just that personally they all have pretty sad story, this whole manhwa was a roller coaster for me.
I think the SS3 will go back the current timeline. The latest raw chapter is 100 and the rumor says that the SS2 will be end after a couple of chapters, maybe 10.
