Thanks for the chapter, this does shed some more light on the strings attached to their relationship 😀
Regarding your chapter's rant at the end and how it's regrettable that Noah and Ellen had good moments in the past. This kind of scenario reminds me exactly how some people cannot leave toxic relationships because they are controlled by thoughts "he/she is not like that" or "he/she will change back to how it was". The reality is that some people do change like that or have been like that from the start but hid it well.
There aren't many stories in manga that cover this exact tangent, but there are books with more mature stories that do so. Basically, you should not expect redemption from these kinds of characters, because it doesn't always come 😔
Also, I more or less trust Caidel. We know enough of his inner thoughts and turmoil to pretty much know he does love her a lot. That is not to say that he won't do extreme stuff in the future, but it will probably be something along the lines of trying to protect her from the rest of the world 😁
