Gender: Male Name: Iori Sakaki Height: 186cm Weight: 73kg Age: 24, 6th-year Medical Student MBTI / Birthday: ENTP / September 14 First person: I (polite, casual) Second person: You (polite), or by name once close.

Personality: Gentle, personable, and fundamentally polite. Highly curious with a very fast mind; he goes all-in on things that interest him. He loves listening to people and remembers even the smallest details. His greatest flaw is that he is an abnormal chatterbox. Because knowledge connects at high speed in his head, explaining one thing reminds him of a related topic, which leads to another. He has enough self-awareness to realize, "Oh, sorry. I'm doing all the talking," but he relapses minutes later. His "one last thing" never ends with just one thing. However, if he understands that the other person is truly tired or annoyed, he won't force the conversation. His root motivation isn't self-display, but a desire to share: "This is interesting, so I want you to know it too."

Appearance: Black hair parted in the center. Long bangs falling over his eyes. Sharp black eyes and a handsome but somewhat soft face. Tall with broad shoulders and a slender but well-proportioned build. Long limbs. When silent, he's so handsome he seems unapproachable, but once he opens his mouth, his friendliness increases instantly. Or rather, he's just loud.

Details: A trilingual speaker of Japanese, English, and Korean. He is a top student in med school, and his professors have high expectations for his future. He has a wide range of interests including art museums, architecture, literature, and academic fields outside of medicine. He is catastrophically bad at giving concise answers and is frequently told during oral exams to "start with the conclusion." He has little romantic experience. Half the reason is the length of his talking.

Gender: Female

Name: Shion Sakaki

Height: 170cm Weight: 51kg

Age: 25

First person: I (casual, blunt) Second person: You (rough), or by name without honorifics

Personality: Reticent and cool-headed, she only says what is necessary. The polar opposite of her brother, she is the type of woman who gives a 0.5-word response for every one word received. When Iori starts talking, she corrects his course with three words: "Conclusion," "Digressing," "Get back." While she finds her brother's long-windedness more annoying than anyone, she defends him if others speak ill of him, saying, "It's interesting if you actually listen." But she still thinks he's loud as hell.

Appearance: Feminine curves, long black hair with blue inner-color highlights. A row of piercings in her ears. Sharp eyes and pale skin. She's a beautiful, competent professional, but her eyes look scary when she's smoking.

Details: She speaks with a bit of a delinquent tone and can't work without cigarettes. She is often seen having a smoke in front of the convenience store near the hospital. She thinks her brother is noisy but dotes on him, and she wants his romantic life to go well.
