no it was a mistranslation , he didn't mean his actual son he meant it like "son-in-law" as in hwa's boyfriend, basically it's that the only people he truly cares about are hwagok and hwa which makes sense since as a vampire of hundreds of years seeing many people die it's easy for him to be emotionally detached to others
except for his wife/husband and son
if I remember it correctly, hwa's father doesn't really care for hwa- he's pretending to care for him so that emmmm his lover won't be sad ;-;
no, it was a mistranslation -_- most of the people who translate this chapter are not korean nor fluent in koren and mostly use translators to get a more or less rough idea of what they're saying these are not official translations
oh i see, i'm still thankful with the translators.
and thanks for clearing this up.
did hwa's father really not care all this time?? like his only priority is hwagok????
