The sands of time
Reaper to the mansion after being gone for hours and Natasha was getting ready for the night. he checked up on her, and after seeing that she was alright, he left for his room without drawing her attention. He was paying more attention to her and he didn't even realize it, taking her safety as his second job.
He entered his room and without opening the door just apparated through to the inside. He went into the bathroom after taking off his clothes and stared at the now-cold water. Perhaps it was better than the warm one to reduce the heat on his body, but he knew that nothing would be able to reduce what he felt and had come to understand that it was only she who could do it.
