As a bodyguard, the most important task at hand is to ensure the safety of the person you protect.
One particular bodyguard in South Korea has been quite an exceptional man, not just to former K-Pop idol group Wanna One, but also for the fandom, Wannable.
Not only did this man do a superb job ensuring the safety of Wanna One members, he knew the names of each fandom of individual group members.
Fans have been touched by his efforts that they even created the nickname, 'Dear Ahjussi' and a social media account for him, as well as a fan-made hat.
His name? Mr. Ko SeokJin.
It wasn't just the fandom name of particular individual Wanna One members' fandom names he knew, but also the fandom name of NU'EST as well.
