Here comes my favourite character!!!

For anyone reading this after watching the kdrama and are confused abt names. The second names of the characters are the same in the kdrama, so gray yeon = yeon sieun, ben park = park humin/baku, alex go = go hyuntak etc. Also the manhwa has a few characters who werent adapted like gerard jin/jin gayool. So if theres a character u dont recognise its most likely because they weren't adapted.
