They*
They are twins
No? One is way younger than the other but yeah they do look exactly alike to be twins
The summary description for this says they're twins, not that they're 31 and 27.
Okay cool, maybe that is an error bc chapter one in Korean and English states one is 31 and the other is 27
I think the description is wrong. Otherwise the age gap is wrong. Hahah.
But I would say that the older brother for sure in one of the later ch. So yeah. I'm sure they messed up. Unless they meant something like "mirroring" or "mirror image" or "spitting image" likes twins. Cuz Eun- Il is def using PilWoo for his "twin mirroring image of JeHeon".
The look more like twins than brothers
