So, how old is Hoseok's sister? Unfortunately, we don't have an exact answer, as her age hasn't been publicly disclosed. But we can make some educated guesses based on Hoseok's age and the fact that she's younger than him.
We know that Hoseok was born on February 18, 1994, which makes him 29 years old (as of 2026). If we assume that his sister is at least 5-10 years younger than him, that would put her in her late teens or early twenties. But again, this is just a rough estimate!
In K-pop, it's not uncommon for family members to be kept out of the spotlight. But that doesn't stop fans from being curious! Hoseok's sister might be a student or pursuing her own interests, but we'll just have to keep on guessing.
