Well... that sure is giving me a flashback... knew a girl that was very much bullied because she was taller than others in her youth, calling her "giraffe" or "two eyed cyclop" because she wore glasses (wtf) by everyone including her family, was even mistaken for older men for being older, that didn't work out on her psychology as being low self-esteem took any affection as something more. Probably can guess what happened to her...
Anyway met her when she was 25, already broken, tried my best to fix whatever damage was done, we were 8 years a part but adults in mind (kinda, she was still childish due low self-esteem)... unfortunately meeting scumbags in her life put too much damage to her, was alcoh addiction and even if put all my strength, therapy and support... couldn't undone what was destroyed. The worst was physical and mental abuse when she was even "tipsy". Didn't work out after 6 years...
Anyway, back to the story, Natsumi isn't interested in Aoi sexually, although had impression of her being older is seeing her as a 12 year old girl, doesn't even see her romantically. It's more like friendship so far, they just need to stay within the line and wait till her hormones stabilise.
Aoi found a gam, Natsumi wouldn't abuse her it seems, something some people can take advantage of.
Thanks for scanlation!
