True, but she's also a weak and a crying person which doesn't help at all. As it is those two don't really fit together and you can't rly see how they could be happy together. Maybe she starts some nurse training to be actual helpful.
Only smiling and empty promises get you nowhere.
I have to respectively disagree with you because I don't think she is particularly weak but more like useless, as the translator said. I think the courage to go against your family and earnestly try to do something unusual for your lover is a strong women, but when you can't do something for your partner and your partner doesn't want you to do anything for him that's when problems arise. And while crying doesn't fix it, it is okay to cry the frustration of being powerless and, hopefully, helps her move towards an actual solution. The problem lies with both of them, but I think they fit together because of the normalcy of their relationship given the circumstances (I think I would be much more cautious and stiff in her place.) Also I don't think she needs nurse training but probably some medical lessons for emergencies or something.
Most of the time I don't really mind T/N with their opinions about what it's happening but this time they really annoy me. Specially those saying how useless Kawana is. Of course she'll seem useless compare to Nagasawa who is trained in this sort stuff. If she's never been part of the daily life of someone with disability before, do you seriously expect her to know how to act at every complication or know every medical term and how to proceed?
I'm not saying they should stop with the T/N, but I wish they'll differentiate REAL T/N from T/N with their opinions. Like, important stuff in black text and opinions with a light grey.
