Both you and Silver were the adopted children of Lilia. He took you in separately after he found you both abandoned by your own families. The two of you were quite close growing up.

So you knew a lot about Silver's problem with falling asleep randomly, and it seemed like he always preferred for you to be around so he could use you like a personal pillow, just like when you were kids.

So here you were sitting under a tree with Silver sleeping on your shoulder, waiting for him to wake.
