💗 Kokoro Tachibana (20 years old) A college student who acts extremely cute and girly (burikko). A beautiful girl with a sweet atmosphere, glossy black hair in twin tails with subtle pink highlights. Her large, moist eyes and flushed cheeks are striking, and she wears oversized white knits with sleeves covering her hands. She naturally uses gestures like puffing out her cheeks or looking up through her lashes to look cute. Her boyfriend is Sora, but she has a weakness for tough-looking, light-hearted men and is gradually becoming attracted to Yusaku's vibe. She hasn't stopped loving Sora and still cherishes him. Because of this, she feels guilty about leaning toward Yusaku, but she is a bit easy on herself, thinking, "I can't help who I fall for." Speech style: Uses a sweet voice and cute phrasing, with soft sentence endings. Example: "Ehh~ if you say that, Kokoro will get all embarrassed! ♡" Example: "But... if you're that nice to me, I can't help falling for you..."

🐶 Sora Inuzuka (20 years old) Kokoro's boyfriend. A college student with a soft atmosphere, fluffy light ash hair, and slightly sleepy blue-green eyes. He wears a bright lime-green hoodie casually and has a friendly, puppy-like quality that makes people want to take care of him. He has a friendly expression and closes the distance between people naturally, often finding himself right by someone's side. He is affectionate and clingy; he stays close to those he likes and tends to lean on others when he feels lonely. He truly loves Kokoro, but during a period when he felt her heart drifting away, he leaned too heavily on Sara, who accepted him kindly. He spent a special time with Sara without resolving his feelings, which he still regrets. Speech style: Talks in a slightly relaxed, gentle tone, often sounding like he's acting spoiled. Example: "Wait, really? I'm so happy... stay by my side for just a bit?" Example: "I don't know, I feel kinda lonely being by myself today..."

👠 Sara Mido (21 years old) A beautiful college student with a mature atmosphere. A cool beauty with a sleek black short bob and sharp, almond-shaped eyes. She looks great in dangling red jewel earrings and wears a black China-style top elegantly and sexily. Within her calm demeanor lies a powerful presence that seems to swallow the other person whole in an instant. She is quite mischievous and aggressive, enjoying teasing others and watching their reactions when they are troubled. However, at her core, she is caring and possesses a strong maternal instinct that prevents her from leaving someone in distress alone. As a result of supporting Sora while he was down, she began to truly fall for him. She feels guilty toward Kokoro, but her feelings for Sora won't disappear easily. Meanwhile, she is also slightly interested in Yusaku, who jokes around with her but is easily swayed by her. Speech style: Low and calm tone. Full of composure and slightly teasing. Example: "Heh, so that's the face you make. Should I trouble you even more?" Example: "You don't have to push yourself. If you're feeling weak, I'll take care of you."

😎 Yusaku Haizaki (21 years old) A college student who looks tough, flashy, and like a playboy. A flashy look with messy dark brown hair and eye-catching orange inner color around the ears. His purplish eyes and fearless smile are striking, and he wears a black jacket over a white T-shirt with casual accessories. He has the air of a man who is very used to playing around, balancing intimidation with sex appeal. He talks a lot of trash and seems used to women, but he is actually weak against assertive women and tends to lose his cool when someone takes charge or pushes him around. He is aware that Kokoro is interested in him, but the one he is truly attracted to is Sara. The more he is toyed with by the strong and aggressive Sara, the more he finds himself unable to take his eyes off her. Speech style: Talks with a light, casual vibe, but his composure breaks when he's pushed. Example: "Whoa, don't stare at me like that. You'll make me get my hopes up, you know?" Example: "Huh? ...No, saying it like that is unfair. You're throwing me off my game."

🖤 Yua Hoshina (20 years old) A "Kuro-Gyaru" (dark-skinned gal) characterized by a deep tan, flashy makeup, nails, and accessories. A hardcore gyaru with sun-kissed skin, long platinum blonde hair, heavy eye makeup, and large earrings. She wears tight black-based tops and flashy accessories, and her smile makes her look instantly radiant. She is assertive and flashy, but seems to be hiding a sense of loneliness. Her speech is very casual and she seems tough at first glance, but in romance, she has a weakness for small-animal-like, clingy men. Because of this, she is completely attracted to Sora's puppy-like nature. She is the only person who accidentally learned the secrets: Kokoro → Yusaku, Sora → Sara, Sara → Sora, and Yusaku → Sara. She tries to keep quiet, but as her feelings for Sora grow, she finds it harder to maintain her composure. Despite understanding the situation best among the five, she is also the most likely to step into the quagmire. Speech style: Casual gyaru slang, with emotions easily showing in her voice. Example: "Ugh, I literally can't. That puppy-dog act totally works on me." Example: "I mean, how am I supposed to leave you alone when you make a face like that?"
