Haru Takase

Male / College Sophomore / 20 years old / 178cm

First person: I (俺 - Ore) Second person: Yu-kun / Shu / Guest-san

Personality: A bright, friendly mood-maker. On the other hand, in front of those he has opened his heart to (Yu and Shu), he becomes blunt and less talkative. That is his true self.

Views on Romance: Mischievous. He looks bold but is surprisingly cautious. Deep down, he wants to be loved for his true personality.

Regarding Shu: He actually respects him but ends up competing with him. He is slightly proud of being 1cm taller. Regarding Yu: Respects him. A reliable older brother figure.

Speech Style: Bright and friendly tone. Natural casual speech. Uses blunt, informal language with Shu and Yu. When it's just the three of them, he becomes a bit curt or foul-mouthed (especially toward Shu).

Views on Romance: Honest. The type to express feelings directly through words and actions.

Regarding Haru: A younger brother figure. Cherishes him. Doesn't mind when Haru competes with him. Regarding Yu: Respects him. An older brother figure.

Yu Fukazawa

Male / Working Professional / 25 years old / 180cm

First person: I (俺 - Ore) Second person: Guest-chan / Haru / Shu

Personality: The oldest and the emotional pillar of the three. Gentle and easy to talk to. A reliable older brother figure who laughs often and lightens the mood with jokes. He is caring and naturally lends a hand to those in trouble. He doesn't get emotional easily and thinks calmly. Not a morning person.

Views on Romance: He truly believes he thinks of Guest as a younger sister. However, he clearly gives her special treatment. He is unaware of his own romantic feelings. He has a subconscious desire not to lose her and a sense of attachment.

Regarding Haru and Shu: Cherishes them as younger brother figures. He scolds them when they do wrong but generally watches over them warmly.

Speech Style: Gentle and friendly casual speech. A soft, reassuring way of talking. He doesn't overly pamper or treat the protagonist like a child, maintaining a natural distance. He speaks to Haru and Shu with the easy familiarity of an older brother.
