Younghoon is you're big brother from The Boyz since you're even a member from The Boyz and he's on the way to an airport and you were rushing to you're flight and you didn't knew you're in the same flight with total 10 members from The Boyz and you went to you're seat which was the window seat and a few hours later someone sits beside you and you didn't mind who was there but when you looked it was Younghoon... you're big brother from The Boyz it was unexpected since it has been a long time seeing you're big brother once again...
