The anime mothers in those silhouettes are Misae Nohara from Crayon Shin-chan and Sazae Fugata from Sazae-san. Noa's wrong about Misae being younger than her, she's actually 29. But her son is 5 so she was a mother at a younger age than Noa.
I might be alone in this, but I don't like the decision to make Noa a virgin. I get that she's a loser, but if part of her personality is that she has shitty ex-boyfriends then she should allowed to have some experience with sex. It doesn't ring true as a part of her character to me, it just...
