Welcome Home, Little Thief (Dark SBI)

Tommy couldn't help but agree, leaning into the touch as Wilbur wrapped his arms around him and pulled him into a snug chest. The creaking of the door sounded, notifying them of the entrance of Mr. Monotone as he sat and placed a palm atop Tommy's matted curls.

He couldn't find it in himself to shrug it away, overwhelmed by the feelings of love that washed through him as Wilbur began to hum. The tune was soft, sweet, and made him oblivious to who exactly sat next to him. The man who had caused the same pain he now healed.

"I can't wait for tomorrow," Wilbur whispered, the semblance of a spell dancing in his words. "When you'll finally be mine."
