Also, the story being set in old times doesn't justify anything. Some things can't be excused because it's a "Culture" or a"tradition". Yes, it was normalized in old times but that doesn't make it ethical or moral.
You are free to like it, i don't judge anybody but some people might feel uncomfortable even if it's a fiction and that's totally fine imo.
yep literally i had the same thought.. like it rlly wouldnt kill the artist to make her look her age... shes literally half his size.if the purpose was to make her look fragile they couldve executed it better... idk and people are justifying it saying its "only" a four year age gap but its literally fetishizing how little girls look...

The problem is not 4 year gap or sexual interaction or whatever. It's just that Nina looks too young in this art style. She doesn't look 15 she looks more like 12 to me and the ML doesn't look 18 he looks 25 or something. That kinda irks me a bit honestly ngl.
If Nina at least looked a bit more mature it wouldn't feel as much weird maybe??
