Murakami's face at the bottom of page 11, she seriously thinks that Moritani is just asking to know her body better (which isn't what Moritani means at all). I'd say that Murakami truly believes that the only reason someone would want her is for her body. That is she believes nobody would want her for herself, not even as a friend. I'd also guess that she has a lot of experience backing up that belief.
The way the two became acquainted back in chapter one fit that preconceived notion. Moritani is going to have to do something drastic to start shaking that belief loose. The stage was set in this chapter, but can Moritani do what has to be done? Moritani is like I used to be when I was young; I know what it's like to be a person who fades into the background, who doesn't make waves, who never does anything drastic. It took me decades to somewhat break out of that mold.
I've been iterating from the beginning that I think Murakami just has low self-worth and self-awareness. She's been chewed up and spit out by too many...not necessarily abusive, but rather short-sighted and unkind partners in her past, that she's let it get to her head that her worth is only as much as what others project on her, and she's gotten unlucky (until now) in finding a proper significant other.
Murakami I think does legitimately like Moritani, and Moritani is putting a lot of effort toward the relationship. It's finally Murakami's turn for a wake-up slap.
I agree. Perhaps on the start they have this misunderstanding but as time goes by Moritani is clearing the air infront of her.
