The Hunter thing would be good. Imagine that it was a character that the MC knows he should kill but cannot since he is protected by Isabella, that the traitor is Alicia that she is manipulated by Hunter and she helps him with the sister and mother of the MC that he does not care thinking that he is only a lover but wants to kill him when he sees that the affection counter for him decreases but to his horror he cannot since he is protected and he only sees his mother become what she was in the another life and his dear sister to follow her, this would make him value his women more and not see them only as banks. In Eleanor at the end, seeing how he is doing things, she is fighting with her past and her love for the MC would reach 100 when she sees how he fights for them.
Lol I feel im giving suggestions a bit too often and theres no way to include them all lol, so no pressure but heres another one: I'm not the biggest fan of loli stuff most of the time, but I really like the kind of cuddlable girl that just hangs around, literally for holding and instantaneous xxx all the time. I've never seen it in netorare before though. ^^^the important part^^^ Below are specifics that I thought of but arent that important I would like a girl, like I described above, to basically be a long term antagonists toy thats always around them, and although not complete betrayal or anywhere near, more of a in private thing with an antagonist, where although she can love Alex romantically, she still only gives her body to antagonist even without Alex's influence or nature (The thing I want here is less on her part, but more on the antagonist having complete control over everything but her feelings for Alex, due to being addicted to antagonist for example). She could even start with the antagonist. I just want somthing a little little different than the public humiliation and the "doing it because of alex". Also, unrelated, but I would reccomend adding more short scenes throughout like what you did with Alice, that way readers have short scenes even in more plot based chapters, that way you could even add plot chapters more often if you wanted. Sorry for the long comment lol
