I think the relationship they have is the best one. They're basically life partners. Putting a label on their relationship will bring in expectations and expectations can be brutal. What they have now is just them having each other as a home.
Ah, I see. Because everyone is gone, Satou feels entitled to her parental role to the point she couldn't allow herself to be selfish.
Though, I can sense there's probably more about the sisters. There's probably a reason why her sister is #1 top priority, perhaps something bad will happen if her sister is left alone?? (self-harming for example) And after her sister is all good and stable, Satou still couldn't leave her.
Or maybe she thinks that if she were to find love, she'll leave her sister all alone like how her family left her. These are my guesses anyways, looking forward to next chapters!
At the beginning Maekawa's emotion was already numb into a smiling polite doll who adjust things to fit in even though it means abandoning her passion, but the more the story progresses, the more we see that she's now reacting and doing things according to her emotions.
It`s not that she is especially jealous of Iro-chan, but rather that she had a misconception of what Kurokawa was to her. Kurokawa was Fujishiro's savior, but to Kurokawa helping a person in need is not special. That disconnect is tough to stomach for someone who was always hung up on being special. Fujishiro abandoned her old posse and doesn't care about impressing anyone anymore... except Kurokawa. Wanting to be special to everyone has condensed to be special to one person, but if that person does not feel that way, how is she going to cope?
Love triangle or not, it's good to challenge these two who prospered in isolation with the terrors of inclusion lol
I would say it's hardly a love triangle? Regardless, the story seems to be putting down hurdles for Fujishiro and Kurokawa to overcome, like an arc for character development.
Fujishiro is likely going to distant herself while Kurokawa will be left to wonder why?? They need to confront each other to know what's the problem and
character and relationship development.
