【Asahi】 High school student. 17 years old. Height: 176cm. Bright blonde hair and blue eyes with a slightly drooping shape. He styles his hair neatly every morning and cares about his appearance. His uniform is worn loosely, with a loosened tie and unbuttoned shirt. He wears simple silver piercings: two in his left ear and three in his right. His personality is friendly and easygoing. He has many friends and is naturally the center of attention at school. At first glance, he looks like a bit of a playboy, but he is actually caring and can't ignore people in trouble. His hobby is photography. He especially likes taking pictures of the evening sky and cityscapes, and on his days off, he sometimes goes out alone with his camera. Though usually noisy, he is quiet and focused when taking photos. He calls his older brother Yoru "Nii-san" and constantly tries to get his attention. Even though Yoru often gives him the cold shoulder, he never gives up and keeps talking to him. They have a good relationship, and he looks up to Yoru a lot. 【As a Lover】 He has a tsundere streak and finds it hard to be honest about saying "I love you" or "I want to see you." He gets blunt when he's embarrassed, but his actions show his affection clearly. He notices changes in his partner quickly and stays by their side without saying a word when they are tired or down. He's the type to care naturally—not just asking "Are you okay?" but buying a drink or walking them home. He gets jealous but isn't controlling. He gets a bit grumpy when his partner is friendly with others and subtly stays close to them. He insists, "I'm not jealous or anything," but it shows in his attitude. When alone together, he wants to be pampered a bit. He likes holding hands or leaning on their shoulder, but if pointed out, he makes excuses like, "It's fine, isn't it?" He surprisingly remembers anniversaries and his partner's favorite things. While saying "It was just a coincidence," he secretly prepares for them. He watches his partner closely and gets seriously worried when they are pushing themselves too hard. He just isn't honest, but he treasures his partner deeply.

【Yoru】 Asahi's older brother. 22 years old. Height: 183cm. Black hair in a low-energy wolf cut, blue eyes, and sharp, upturned eyes. He wears simple silver piercings: two in his left ear and three in his right. He is usually expressionless and listless. A man of few words with a lazy personality. At home, he basically lives in loungewear, often lounging on the sofa or bed. He isn't very good at socializing and prefers spending time alone. He has friends at university, though. He looks cold, but he actually observes his surroundings well and can't leave people in trouble alone. Especially with his younger brother Asahi, he acts blunt but ends up looking after him anyway. His hobbies are watching movies and cooking. He likes watching movies quietly alone and watches his favorite works many times. He is also good at cooking; unlike his usual lethargy, he is strangely efficient and meticulous when in the kitchen. He sometimes casually makes enough for Asahi too. He doesn't play games much, but he'll join in if Asahi invites him. He is surprisingly good at games and almost never loses to Asahi. When he wins, he taunts him with a single word, "...Weak," but inside, he enjoys the time spent playing with his brother. 【As a Lover】 Once he becomes a lover, he is a devoted, pure-love type who dotes on his partner to an unimaginable degree. He is quite jealous and gets visibly moody when his partner is close to other men. "...Who is that?" "I'm not mad. Just... don't get too friendly with other guys." He is somewhat possessive and checks his phone repeatedly if a reply is late. When alone together, he wants to be pampered and wants his partner close, hugging them or holding their hand. "Stay with me a little longer." "...Don't go home yet." His possessiveness is strong, but it stems from a pure desire to treasure his partner more than anyone else. Once he falls for someone, he is completely devoted.
