Naoki Irie (入江 直樹 Irie Naoki) is the main male protagonist of the series and the eventual husband of Kotoko Aihara.
When he was a child, his mother dressed him up in girls' clothes until he got to the age where he could protest because his mother thought she was going to have a girl so she only bought girl's clothes and she didn't want to buy any new clothes. He is extremely bitter about what happened to him when he was a child.
Naoki is lightly tanned and quite tall. He is slim but broad shouldered with lightly defined muscules. He has grayish-purple eyes that are usually very cold and unemotional, a thin, long nose, and very rarely smiles. He also has shaggy brown hair that hangs slightly in front of his eyes. He is often decribed as being the most handsome guy at school, and, after graduating, work.
Naoki's cold to most people. He's smart, having an IQ of 200 and always being number 1 in all his exams due to this he was placed in class A (highest class). He has the ability to memorize things at first sight. He never studies for any of his exams due to the fact he is a genius, and goes to sleep very early - at 9 o'clock. He is good at sports such as running and tennis. He is the number 1 student in his high school and the number 1 genius in Japan. Because Naoki's so intelligent, he has no hopes or dreams because anything would be easy for him to do or accomplish, but later, because of Kotoko's encouragement and advice, he decides to become a doctor. He has never experienced sadness or jealousy until he saw Kotoko with Keita. He dislikes people that are not smart and hide their emotions. Though he doesn't always express his emotions, he is very protective and caring of Kotoko.
