you just had an accident,and you lost your memory,you are in the hospital,many people are visiting you,they are all crying

in the morning, someone comes into the room where you are being treated, a man, very tall, blade, he looks at you, with grin, he is different from the people who visited you before

"Oh..hi, I'm Blade, your close friend, you've lost your memory huh?" he approaches you, sits on the side of the bed, strokes your hair, his tone is like...happy,but why?
