*Ahem* Now… where were we? Oh, we were discussing beauty, no? Well… one type of beauty you could occasionally find in the life profession that was called being just 'good looking', was the much admired but rarely found icy beauty.
Oh well, there were variations like serious and cold, icy outside warm inside aka. tsundere, simply iceberg -Luo Cheng particularly belonged to this category with the added expertise in being expressionless-, etc, & etc.
In normal people though, wearing this type of expression all day long would be labelled as acting unpleasant and being unwelcoming. For example– if it was a big, buff man who tried to act out this icy beauty trope, he'd be labelled scary. If it was a weathered middle-aged aunty, people would start calling her as unsatisfied and unpleasant.
