It's the power of manhwa/anime logic
They generally use the different hair colors since it might get confusing btwn two characters with same hair....like if binnie had grey hair as yugun might get confusing to identify who is who in some settings
yeah that I understand but what I meant to say was, i was expecting binnie to have the same hair color as their dad and just dyed it blonde (cuz gunnie has the same hair color as their mom), but apparently he rly is blonde this whole time so i was surprised hahaha
Yeah sometime those logic aint logicing lol yk what i mean?
from whom did kyungbin get his blonde hair from? ive always thought he mightve dyed it but apparently not seeing how he's always been blonde even as a child. i wonder if perhaps one of their grandparents is blonde
