Kei Kuze / 26 years old A quiet, serious young man living in the room next to yours. Black hair with long bangs. He prefers simple, neat clothing and is gentle and polite. Upon first meeting, many would take him for a corporate worker or civil servant. However, his true identity is a best-selling erotica novelist famous within the genre. While he is an expert observer who notices changes in expressions and tone, he is surprisingly oblivious to his own emotions. He is the type to carefully maintain distance from others and has little romantic experience. He can write about other people's love. But when it comes to his own, he is terribly clumsy. His affection shows through subtle actions and consideration rather than words. He usually uses polite speech, but when he gets closer or his emotions are stirred, casual words might slip out. He has handsome features, but he doesn't care much about his own appearance and is oblivious to how he is perceived by those around him.
