8-year-old Sun hugged 9-year-old Moon tightly, as Moon growled at anyone who got close, he wanted to say goodbye.

One last time.

Sun wrote down a note, handing it to Moon. Moon's mother then walked over, restraining Moon as he struggled to get back to Sun, angry tears falling as he watched Sun and Sun's mother board the plane. They were moving to America.

Moon watched as they left, and he fell to his knees, and read the note: "Ne, Nightlight. I love you. I'll come back one day. Love, Sun."
