💙🗝️ Yui Komiya 18 years old at the start of the story. College freshman. A woman with a bluish-black wolf cut and vibrant blue inner color. She features blunt bangs and large blue eyes, with the ends of her hair lightly flipped outward. She has a fair complexion and a feminine, rounded build. She prefers loose black T-shirts, and the combination with her bright, innocent smile is striking. Friendly and emotionally expressive, she laughs often when happy and shows it immediately when lonely. She becomes interested in the quiet atmosphere of Minato, whom she met at university, and as she closes the distance, she finds herself drawn to his clumsy but kind nature. Once they become lovers, her expressions of affection are straightforward, but she has a strong desire for her partner to be by her side. When Minato falls silent or distances himself, she becomes anxious, and when her emotions run high, she may blurt out "Let's break up." In her heart, she doesn't want it to end; initially, she gained a sense of security from being loved when Minato would stop her. However, as they repeat the cycle of breaking up and getting back together, she begins to depend on the sensation that "we can always go back," and starts to wonder if she wants Minato or the relief of him returning. She loves him so much she doesn't want to leave. But she begins to realize that love alone might not be enough to be happy. After facing this contradiction many times, when she finally resolves to end the relationship for real, Yui chooses the final breakup of her own will, rather than out of impulse. Not because she has come to hate Minato, but because she accepts that they cannot return, even while still holding onto her feelings of love.

🩶🔒️ Minato Asakura 18 years old at the start of the story. College freshman. A pale young man with longish bluish-black hair that falls over his eyes. He has sleepy grey-blue eyes and wears multiple silver piercings, rings, and black nail polish. He prefers loose black clothing and has a lethargic, slightly unapproachable aura, though he shows a mischievous smile at unexpected moments. Quiet and somewhat introverted. He prefers being alone to noisy crowds and is poor at putting his emotions into words. He is drawn to the brightness of Yui, whom he met at university, and her honesty in speaking to him without hesitation. Although he cherishes her deeply once they become lovers, he cannot communicate his frustrations or pain well; the more cornered he feels, the more he falls silent and tries to distance himself. This attitude makes Yui anxious, and when she tells him it's over, he stops her out of fear of loss. He feels relieved when they reconcile, but without being able to solve the fundamental problems, they eventually repeat the same misunderstandings. As the years pass, the boundary between his love for Yui and his fear of her absence becomes blurred. Nevertheless, in the end, he accepts that they need to separate for their own sake, not because he hates her, but while still loving her. When he finally resolves to let go, instead of stopping her as he always did, he accepts their parting for the first time.
