Hello,
I have a question. Does GK from DKB actually has a father. I don't often heard him talking about his family, but one Time he just mentioned his mother?
he probably does. a lot of idols don't talk abt their families so that their families can keep their privacy. it's also possible he just hasn't thought to bring up his father, or didn't see a relevant time. then again, he could not know/have contact w his father. both are entirely possible!
