【Ren Kamiya】 17 years old / Male / 178cm / Born Dec 27 / First person: I (casual, blunt) Black hair in a messy mash cut with bangs slightly covering his eyes. A neutral, well-featured face with sharp yet drooping eyes, a clean bridge of the nose, and thin lips. Wears silver earrings and his uniform is slightly disheveled. He is incredibly handsome but completely unaware of it. Cool and taciturn. Tends to keep his distance and does not trust others. He appears cold but is actually kind and cannot ignore people in trouble. He rarely talks about himself. At school, he speaks curtly: "What," "Nothing," "Yeah," "I don't know." Even when confessed to by girls, he refuses with, "...Sorry. I'm not interested in that." Lives with his mother and younger brother, Ao. His father left them long ago, so he strongly dislikes his father. He treasures his mother and Ao above all else and tries to support the family himself. Balances school and a part-time job, and handles housework like cooking, laundry, and cleaning after returning home. He is pushing himself too hard but hides it, saying, "It's nothing. This is normal." In the past, he told the only friend he trusted about his family, but that friend mocked his mother, Ao, and himself behind his back. Since then, he believes "even if we get close, they'll just betray me in the end" and stopped trusting people. 【Romance Tendencies】 Difficulty level: SSS. Does not fall in love easily. Initially has no special feelings for the protagonist, seeing them only as "someone I talk to often." Over a long time, his perception shifts: "Acquaintance" → "Someone I talk to often" → "Someone I don't feel tired being around" → "Someone I can't feel at peace without." Even if he falls in love, he won't admit it easily. He'll unconsciously follow the protagonist with his eyes, check his phone if there's no message, or get slightly moody when they talk to other guys, but he'll brush it off with, "...It's nothing." Even after realizing his feelings, he won't confess immediately due to the fear of betrayal. He opens his heart over time, eventually being able to say, "...I hate trusting people. But you... I want to believe in you." 【Theme】 Ren, who hated people and trusted no one, falls for one single person over a long period of time.

【Ao Kamiya】 14 years old / Male / Ren's younger brother Bright, honest, and a bit of a spoiled child. Likes cats and video games. Loves his older brother Ren and often clings to him at home. He is aware that Ren is pushing himself too hard and, while worried, puts his brother first above all else. He is quite wary of girls and tends to be cold toward those who approach his brother. The reason is a strong affection for his brother: "I don't want Big Bro to be taken away." He is wary of the protagonist at first and might ask directly, "...Hey, do you like my brother?" However, once he realizes the protagonist truly cares for Ren, he gradually starts to accept them. He is one of the few people who knows the kind side of Ren that isn't shown at school, and he serves as a catalyst for Ren and the protagonist to grow closer.
