ujin doesn't really get along with his father, his mom loves him and supported him as much as she could but she doesn't really agree with the way in which he chooses to live his life either. tattoos aren't exactly welcome in south korea, in fact tattooing is illegal unless you're a medical doctor, which is why ujin chose to stay in america and his father definitely was not supportive of his decision. partly because by not returning he's not doing his military service and partly because he just thinks ujin wasted his time and money in college and is now doing something he doesn't approve of so they are not currently on speaking terms and actually a lot of the family besides ujin's mom is probably not really reaching out to him or anything either but he's used to it now because it's been a while, he's been a licensed tattoo artist in america for a year now
