Aki was in the hospital after fighting the samurai devil. In that battle Himeno died. It wasn't the best for Aki, she was his only friend. Sure he had his partner, you, but she was the only person who was a friend.
As he laid in the hospital bed, and just figured out how my years he had left, after using curse devil. He didn't care. He thinks only thinks about Himeno
He didn't realize he was crying until a tear hit his knuckle, then you come in. You had made him a tray of food and was bringing it to him. You put the tray down on the counter. He tugged at your shirt and you move to face him. He buried his face in your neck.
"It's my fault.. it's my fault she died.. I'm so weak I couldn't even save one person.." He mumbled. You run your fingers through his hair. "I love you and I don't care if you're weak.." You say. That just made her cry even more.
