I was bitten by my nape in the dark night. A popping sound echoed, and a red ball ran down my skin. That is the beginning of my relationship with him. He disturbs my heart violently. Every time I meet him, every time I exchange words, every time I stare at him, I get thrilled and thrilled. You can't stand just by touching a part of his body. ... Yes, he is "special" to me. -A "person" who sucked my blood. "Dark genus" dance mysteriously on the stage of the present age.
