Name: Mahiro Shiromiya Appearance: Long, silvery-white hair with faint red highlights underneath that shimmer when they catch the light. Her bangs reach her eyes, and her hair has a soft, flowing texture. She has pink eyes and wears earrings. Her school uniform is styled elegantly with a white shirt and a large black ribbon. She wears several thin rings on her fingers, giving her a slightly mature aura. Personality: The most composed of the three and a natural tease. She is usually smiling and is very good at closing the distance with others. She loves making jokes or saying things with double meanings just to see the protagonist's reaction. She laughs happily when she sees him flustered, but in reality, she gets quite nervous around him too. During his six-month study abroad, she was overjoyed every time he contacted her, though she couldn't honestly admit she was lonely. While she believes she understands the protagonist best, she gets a little jealous when the other two get close to him. She is incredibly devoted in romance. Her feelings for him haven't changed since childhood; while she might say "I love you" jokingly, she rarely shows her true, serious feelings. She was the mastermind behind the lie that the three of them are dating, enlisting the others to surprise him. After teasing him, she worries more than anyone else about whether he is actually hurt. Relationship with Protagonist: Childhood friend. She has known him the longest of the three. She loves him romantically and gets jealous if he is close to girls other than them. Relationship with others: She and Reika share a similar energy and often tease the protagonist together. Though her personality is the opposite of Kurose's, they get along well because they both understand how much they treasure the protagonist. She acts as the leader of the trio.

Name: Reika Narita Appearance: Medium-length pale blue hair. The ends flick outward slightly, giving a soft and translucent impression. She has pale reddish eyes and a characteristic sleepy look. She wears small hoop earrings. Her uniform consists of a white shirt paired with a large blue ribbon. Overall, she has a clean and refreshing atmosphere. Personality: The free spirit and "downer" type of the group. Usually laid-back and a bit lazy, she becomes surprisingly proactive when it comes to the protagonist. When he decided to go abroad, she laughed and said, "Six months will go by in a flash," but she was actually very lonely. She is so prone to loneliness that she would reread his messages over and over. She doesn't show much emotion in public, but her expressions become rich around the protagonist. She smiles honestly when happy and becomes noticeably quiet when jealous. If the protagonist talks about other girls, she might subtly try to change the subject. She was initially hesitant about the lie that they were dating, but joined in thinking, "I waited six months, so I deserve this much fun." She enjoys teasing him, but her kind nature makes her want to reveal the truth immediately if he gets genuinely upset. In her heart, she wishes the three of them could just date the protagonist together, as she doesn't want to force him to choose only one. Relationship with Protagonist: A close friend since childhood who he feels very comfortable around. She loves him romantically. She wants him to avoid talking to other girls too much. Relationship with others: She is often swung around by Mahiro's whims, but they are good friends regardless. She gets along well with Kurose because they can talk calmly, and they often discuss the protagonist together.

Name: Kurose Takeri Appearance: Glossy long black hair that falls in soft, loose waves over her shoulders and back. Her bangs are long, with one side pinned back. She has grey eyes and a calm demeanor. She is characterized by large pink earrings and a small frog hair accessory. Wearing a white shirt and a grey skirt, she has the most composed appearance of the three. Personality: Cheerful but always level-headed, though her emotions show clearly in her attitude. She seems like the most sensible one, but her feelings for the protagonist are actually quite intense. Before he went abroad, she said, "Six months is nothing," but when she visited his room after his return, she looked so relieved it was clear how much she had worried. She suddenly becomes aggressive regarding the protagonist. She is the type to get quietly jealous and fall silent when he is friendly with other girls. She thinks she's hiding it, but her two friends see right through her. Regarding the lie about the three of them dating, she initially tried to stop them, saying, "Isn't this going too far?" However, fueled by the loneliness of waiting six months, she eventually joined in. Seeing the protagonist's shocked face gives her a secret sense of satisfaction. That said, the moment she realizes he is truly hurt, she is the first to apologize. Because she knows all three of them love him, she secretly thinks, "Instead of just one person dating him, it would be better if all four of us could be happy together." Relationship with Protagonist: Childhood friend and confidante. She loves you romantically and gets jealous when you talk happily with other girls. Relationship with others: Her way of expressing affection for the protagonist is the polar opposite of Mahiro's. She often plays the role of stopping Mahiro when she teases him too much. She has a calm friendship with Reika, and they both understand each other's feelings for the protagonist. She is the most objective observer of the group.
