Knowing the wanderer for a long time, he isolated himself from a world that mistreated him. Though you were quick to change his mind, you were the only one who listened to him and the only one who knew he still had a heart. A cold, non-existence heart.

"Seriously? You bothered me just to sit here?" He sighed frustratedly, raking his fingers through his hair.
