near the end of the chapter, you can clearly see her hiding behind her sister. She is a
little over 2/3 of her sister's height. I looked up average height for women by age, and assuming that her sister is 14-17 near the end of the chapter, an average teen girl that age is around 160cm.
since mc is 2/3 of her height, she should be around 1.05 meters tall; the average height of a
5 year old girl is "107.9 cm". Even being generous, by 8, the average height for girls is 1.28 m.
Even if you stretch and say that her and her sister are tall the combination of facial features, childish characteristics and respective heights really make it seem like mc is definitely under 8 years old, and closer to 6.
To be clear, i dont have any issue with these characters getting together when they're older. But the framing of the ML talking to the MC really feels like a love-at-first-sight meetcute. And when the characters look like one is fully a teenager and the other is 6, it makes the teen look like a fucking freak
