Well basically she's older then him... But with the two year growth period she looked the same but with longer hair, and he looks like hes like 16, so I just think thats how they are drawing her?
It's probably just the art style
Just like in castillo
They made bodyguard look so old but the age difference wasn't too big
But then again
It was kinda big in that manhwa
But the romance happens after main character became 18 soooo
Idk
I don’t think he was blushing cause he was attracted to her he was probably just flustered cause she’s the only person in his life to ever be nice to him
did they tell us abt the ages of any of them- cause like mc is 5, then cahil looks 10-12 and he's blushing for a 5 y/o, some don't feel right
