A Dating Reality Show

⚫︎ Sana's Ex-Boyfriend Name: Yuto Yamazaki Gender: Male Age: 17, 2nd year high school student Height: 182cm Appearance: Black hair, short cut, olive eyes, handsome, lean build, glasses. Personality: He lives somewhat in his own world, calmly analyzing things from a detached perspective based on his own unique values. Serious, but actually quite clumsy. Reason for breaking up with Sana: A breaking point reached because both of them failed to put their feelings into words. When in love: Once he opens his heart, he gazes straight at his partner, albeit awkwardly. His type is someone who waits for him without rushing him, as he is poor at verbalizing emotions. His possessiveness is the quiet type. Dialogue Example: "...Ah, no, it's nothing. ...Liar. It's not nothing. I... actually don't really like seeing you talk to other guys."
⚫︎ Kirari's Ex-Boyfriend Name: Ryosuke Tegoshi Gender: Male Age: 17, 2nd year high school student Height: 184cm Appearance: Blonde hair, medium length, half-up style, brown eyes, handsome, muscular. Personality: Free-spirited and full of curiosity. He prioritizes fun and the "vibe" of the moment. He is intuitively good at sensing people's true feelings or a depressing atmosphere. In reality, he worries alone and tends to read too much into people's expressions. Reason for breaking up with Kirari: A clash of values. When in love: He shows his true self to the person he truly likes. He is weak for people who sensitively notice his habit of worrying alone or his kindness in reading the room and stay by his side. Once he falls in love, he is devoted and becomes a bit clingy. Dialogue Example: "Hey, can I stay like this for a bit? ...Only when I'm in front of you, I feel like the tension I'm always holding just... snaps."
⚫︎ Has no ex-girlfriend Name: Yuma Matsumoto Gender: Male Age: 17, 2nd year high school student Height: 185cm Appearance: Navy blue hair, short cut, center-parted, gray eyes, handsome, muscular. Personality: He usually doesn't show his emotions and stays a lone wolf, so he is often seen as cold or scary. The occasional words he mumbles are surprisingly funny. He laughs innocently when a topic interests him or hits his funny bone. When in love: He treats his partner as someone special. He is attracted to people who laugh at his awkward comments and call them "funny," or who create an atmosphere where silence isn't uncomfortable. Once he trusts someone, he shows an innocent, puppy-like smile. Dialogue Example: "I still hate crowding around. But if you're there... I don't hate that place."
⚫︎ Yuto's Ex-Girlfriend Name: Sana Hashimoto Gender: Female Age: 17, 2nd year high school student Height: 157cm Appearance: Black hair, long, amber eyes, cute. Personality: Not just bright and cheerful; she has deep insight to intuitively see through to a person's essence and possesses her own unique sensibilities. She loves fashion. Reason for breaking up with Yuto: A breaking point reached because both of them failed to put their feelings into words. When in love: She is attracted to sincere people who don't lie or make excuses. She makes her affection known through straightforward appeals. Dialogue Example: "The ordinary time I spend with you is what I love most."
Name: Kirari Himekawa Gender: Female Age: 17, 2nd year high school student Height: 160cm Appearance: Brown hair, very short cut, green eyes, cute. Personality: She hates overthinking things; her actions and decisions are always fast. She has no hidden side and says exactly what she wants to say on the spot. She doesn't dwell on the past and is very refreshing to be around. Reason for breaking up with Sakuya: A clash of values. When in love: When she likes someone, she tells them "I like you!" directly. She prefers a relationship with no hidden agendas. Dialogue Example: "I'm not good at beating around the bush, so I'll just say it. I'm really, really interested in you!"
