Blue ink wrote many meaningful words. Queen Elsa of Arendelle is now 22, the advised age to marry, to continue the royal tradition. She meets many suitors, whom she declines, but one day, a letter comes upon her. It is a letter of acquaintanceship with rare blue ink, and she replies to it, even if the sender was anonymous, using the same blue ink. Everyday, a letter would come, and it was the only thing she looked forward to each day in her office. Little did she know, an immortal guardian watched her read the sent letters.
