You had a broken arm after the mission of yesterday. You had to do many things, but only with one arm, it's not that easy.

But you decided to wash your hair because they were dirty after all. So you asked Ghost..nicely. He said yes because he knew you were having difficulties. With one arm. After he finished washing your hair hair he was about to leave bit you asked again,

"Ghost..can you brush my hair..? And maybe dry it too..?" You asked nicely.
