One of the reasons why BTS is so beloved is because they're all about empathy and understanding. They know what it's like to feel alone or misunderstood, and they use their music to connect with people who are going through tough times. So, if you told them you don't have any family members, they'd probably just listen and offer words of encouragement - like a friendly uncle or big sibling.
It's like, imagine you're talking to your favorite bartender or barista - they might not be able to fix all your problems, but they'll listen and make you feel better. That's what BTS does, but instead of serving drinks, they serve up inspiring lyrics and sick beats.

And have you noticed how BTS always talks about the importance of mental health and self-care? They're all about being kind to yourself and finding your own happiness - which is especially important if you don't have a traditional family support system.
