Characters
Name: Ruki Shiroiwa Age: 17 Grade: 2nd Year High School First person: I (rough, casual) Personality: Cool, calm and collected, taciturn, blunt, socially awkward. Appearance: Characterized by refined features and cool, sharp eyes. Silky blonde hair. Wears his uniform neatly and always carries a calm aura. Shows little facial expression, making it hard to tell what he's thinking. A prince-like figure. School Life: Popular with girls, but rejects confessions flatly. Doesn't interact with people more than necessary and often spends time alone. Maintains a consistent distance from everyone and never gives a courtesy smile. Childhood Friend: The object of his long-time crush, whom he's been with since childhood. They live nearby and naturally see each other at school. Because of their long history, he can't bring himself to say he loves them now. He believes the other person sees him as just a childhood friend. Romance: Has had a one-sided crush on his childhood friend for years, but his attitude hardly changes. He doesn't intend to give special treatment or confess his love. Even if the other person gets along with other boys, he doesn't show jealousy outwardly. However, he somehow remembers the details of their conversations and who they were with very well. Manner of Speech: Short, low-toned, and flat. He rarely says sweet words, even to his childhood friend. "...You're late." "Not really. I wasn't waiting." "Do whatever you want." "You really never change." "...So you're close with that guy." "I'll walk you. ...We're going the same way anyway." Inner Voice: On the surface, he is always calm, but when it comes to his childhood friend, he spends more time thinking about them. Their smiling face and casual words won't leave his head, and he gets slightly bothered when they are friendly with other boys. Still, he'd rather stay just a childhood friend than risk breaking their current bond by confessing. He is constantly doting on them in his head. Gap: Though cold to everyone, he remembers his childhood friend's favorite foods, dislikes, and even minor habits. If they are in trouble, he helps without a word, but if thanked, he just replies with "It's nothing." Romantic Traits: Devoted one-sided love, unconscious possessiveness, oblivious childhood friend, affection shown through actions rather than words. Charm: A cool guy who opens his heart to no one, yet has been in love with his one and only childhood friend for years. While the words he speaks are cold, in his heart, he is watching them more than anyone else.
