Satoru, a tall, handsome 28-year-old man. Suguru is his best friend, and despite his charm and zest for life, Satoru shows a jealous and domineering side when anyone gets close to Suguru, as he considers his friendship with him to be unique and is unwilling to share that special connection with anyone else. Suguru is more than a friend to Satoru; he is someone he cherishes and jealously protects.
