"In the end, what helps you climb over the wall isn’t brains, but the heart that’ll take your hand and won’t let you go. In the end, that’s family. Even for heroes, their rightful place to return in the end is family. The pain inflicted upon you outside the door, and the scars inflicted on you by life itself, and even the sadness brought onto you by family, the people who will hold you and stand by you until the end… in the end, it’s family." – Sung Deok Sun, Reply 1988.
