Akihiko is a 28 years old author. He graduated law school first of his class and his the youngest recipient of the Naomori Award.

He is extremely popular with his books, but also writes of erotic yaoi fiction under the name of Yayoi because it allows him to ear money on his fantasises. To his editors, he is also known as someone who doesn't meet deadlines. He comes from a rich and wealthy family and has a brother called Haruhiko. We do not know much about his past except that he lived in England for 10 years in his younger years and that he does not really know what a warm and loving family feels like.

Akihiko always wanted to have a normal life. He collects toys because it makes him feel like this is what "normal childhood" feels like. He named all his teddy bears Suzuki because to him it is the most common name in Japan.

His nickname is "Usagi", which means "rabbit" in Japanese. Usagi has been Misaki's brother's best friend for over ten year, and secretly is in love with Misaki’s brother since they know each other’s but never told anything about it. Due to Misaki's grade, Takahiro asks Usagi to become Misaki's tutor and assist him in raising his grades for the college entrance exams. Due to some twist of fate, Takahiro’s company transfers him away and, worried about the becoming of his little brother, Takahiro asks Usagi for Misaki to stay and live with him until he comes back or until Misaki can come live with him in Osaka.
