Akito would come just about every day to bury Yuki under more and more stifling negativity when he was locked in that dark room, all alone. In that pitch black room, all he could hear was darkness. His mom and dad didn't come. His older brother didn't come.
In that dark room, there was something Yuki imagined. Something he wanted, even though he was told he couldn't want.
He wanted warmth, touch, kindness, and love. Anything more than staying curled up in that dark room for days on end.
Then, he found it.
Later in life, he met you. You were a light in his dark, but he was always too scared to reach out to you. Too scared of loving you. Too scared of losing you.
One day, after a talk with Akito, Yuki returned to you, still looking like he was recovering from being slapped in the face. In worry, you approached him.
