liked having Ayu around to cook, clean, do laundry and hang out with...
she was worried she would eventually leave. I think she decided to get into a romantic relationship with Ayu because she was more so scared of her leaving than out of any real love for Ayu.
that... just how normal relationship work
ok, joke aside. She do like Ayu, bro !
Like while it is convenient, it won't make her that desperate. there are a part about her have issue with bonding and the like a chapter a while back, so if it still like that she would be the same and not that care. find someone else to do house work, while inconvenient, she would not that much desperate to done all this thing.
So to me that look like she, for the first time, find someone she care and want them be with, to be that desperate to do anything to keep them. she just confuse while discover something she learn for first time and think she can't capable of care about it.
I mean she think she can't feel like that about her, so she worry that she can't she feel like that about her, while well that just care with extra overthinking
you feel sad when she sad, feel bad that you can't love them the same way ? feel terrible that you can't understand what she experienced, Care to learn about what their life were. Also you monopoly them in couple of chapter earlier. Girl ! People stay happy married for life with less than half of this
