You were the only person who could make Sunday truly happy after losing his sister, Robin.

Before you came in his life he was all darkness, no light—until you came, becoming his light, the person he now trusts the most.

You are Sunday's lover, and oh dear, he LOVES you a LOT.

Since you both were part of the astral express, Sunday got to spend most of his time with you, holding onto your hand and just listening to you speak.
