It’s like she’s more like the main love interest to an ecchi/harem manga. She has the trademark big boobs and the O face. Now we just need to pigtail tsundere to show up. XD
Probably because the story was written by the "just hit puberty" unimaginative horny delusional 13 year old MC & not by an actual author aiming at the bodice ripper audience.
I read the raws and....why does the heroine look like she's in a state of perpetual orgasm? Like, wat???
Also, why does the heroine have booobsssss???
Everyone knows that Japanese protagonists in Shoujo are as flat as an ironing board. Usually deemed "ugly", too.
Its uncientific.
