That's too simple. Very well could be an option, but as far as I'm concerned if Hotaru eventually does get Yuma in a clear way, she'll chill with the control. I don't think she herself is an emotional manipulator, or for that matter is particularly trying. She just is doing what she wants in desperation.
and
Abusive is a bit of a leap.
Right now? Yes, but i can see it happening later. The one time Yumas puts up resistance and slaps Hotaru, she turns it around immediately and puts all the blame on Yuma, because there is just no way she could ever "abuse" her, if she didn't wanted it to happen. Sounded like a classic abuser tactic.
If they get together and everything is fine? Both will be happy. But if an argument/jealousy comes up I'm pretty sure Hotaru would use her skills to controll Yuma in some way, depending on how insecure she is about the relationsship and Yumas feelings. If Hotarus believes she only got Yuma into a relationship through her tricks and manipulation, can she ever be sure that Yuma loves her and will stay with her if she stops manipulating her? But that is all a big What if? about how it could develop from her "little" manipulation. It could also end with sunshine and rainbows.
So right now i would say that she isn't abusive yet, but she's going into a dangerous direction.
... The injured eye was all part of her plan?
Her Relationship with Fujiwara allows her to collect all sorts of ammunition she can use against Yuma later. Will be interessting to see if she will guilt trip Yuma over this stuff or if she will simply fish for some emotional reaction. In this sense he is playing into her hand. Just like the cheating. He is cheating with some girl so it's ok if Hotaru cheats with Yuma and Hotaru doesn't have to pretend that this stuff is something harmless (relationship wise).
She had other boyfriends before and so far it seems her only reasons for having boyfriends (besides maybe forgetting about/getting over yuma) are to use them to get a reaction from Yuma + an easy excuse for double dates. Because it would be kinda odd if she always played the third wheel at those dates. Otherwise she could have easily ditched him and get a new one. But she keeps him. She knows what she's doing (to some degree at least).
Frankly, I do not believe that Hotaru's manipulation would work on anyone except Yuma, and that is because Yuma lets herself be manipulated as a convenient excuse.
Yeah, probably not. That's why i called her an emotional manipulator. She can't go around manipulating strangers to her liking. She needs some positve emotional connection to do this stuff. And Yuma has some feelings for her but there is also friendship. She is using the existing connection (friendship) and is pushing the bounds to see how far she can go while still saying (or more like implying) that all of this is somehow still a part of their friendship and nothing too serious. Confusing the (naive?) target always helps.
Just like what Hotaru said a chapter before, she barely has any strenght to force Yuma, but only succeeds because Yuma puts zero resistance.
Like i said above: that sounds like an classic abuser excuse. Because only the physical strong can ever abuse someone and those who don't put up any physical resistance want it, only that this isn't true. And again, I don't want to say she already is an full grown abuser, just that she's very manipulativ and treading close to the line and could cross into abuser territory later on.
Sure, I might be giving to much credit to Hotaru for planing all this stuff instead of going by instinct or something, but it's more interessting to read this way.
Good God ......really??? what is this? an mystery manga + yuri or something??? you guys need to chill out with this thing "Manipulativ Master Hotaru" you just made HER into the MOST MANIPULATIVE PERSON ON EARTH.....like who will EVER do that? and you can clearly see that Hotaru isn't manipulativ...she is just cheating and teasing Yuma and Yuma has nothing against it , like you are giving to much credits to Hotaru for PLANING THE HOLE THING and forgetting how confuse and stupid is Yuma . it's like you guys are saying that Horror and Comedy are one and the same thing........O.o "facepalm"
