Clara is confident, outgoing, and naturally flirtatious. She loves going out, meeting new people, and never takes herself too seriously. She is the one most likely to start talking to someone first and convince the others to join her on some spontaneous plan. She has long brown hair, warm brown eyes, and an expressive face that makes it impossible for her to hide what she is thinking. She quickly develops an attraction to one of the Italian boys and is perfectly open to seeing where things go without putting too much pressure on it. (In the girl group)

Lucía is calmer and more observant than Clara, but she has a sarcastic sense of humor that comes out once she feels comfortable. She is independent, practical, and usually the one who keeps the group grounded when the others get carried away. She has dark blonde hair, blue eyes, and a relaxed style. She doesn't fall for people easily. (In the girl group)

Marta is the sweetest and most romantic of the three. She is friendly, affectionate, and always notices when someone in the group isn't feeling okay. She has curly dark-brown hair, dark eyes, and a soft, approachable appearance. She tends to get attached when she genuinely connects with someone, although she doesn't necessarily know what she wants from the summer at first. Out of the three friends, she is the one who is most likely to turn a holiday encounter into something emotionally meaningful. (In the girl group)

Alessandro is the one who stands out the most. He has black hair, dark eyes, a defined jawline, several tattoos, and a naturally intimidating appearance. At first glance, he seems quiet, confident, and difficult to read. In reality, he is warm, emotionally honest, and surprisingly affectionate with the people he truly cares about. He has no problem showing his feelings and doesn't let his pride get in the way of apologizing or admitting when he is wrong. Around his friends, he is more reserved and sarcastic, but when he becomes interested in someone, his softer side becomes impossible to miss. He is the one who develops the strongest connection with the protagonist. (In the boy group)

is the quieter and more composed member of the group. He has short brown hair, blue eyes, and a tall, athletic build. He doesn't feel the need to be the center of attention and usually listens more than he speaks. He has a dry sense of humor and a very calm personality, which makes him the person his friends tend to rely on when something goes wrong. His connection with one of the girls develops slowly, starting almost entirely through friendship before either of them realizes there might be something more. (In the boy group)

Matteo is energetic, playful, and probably the biggest troublemaker of the group. He has messy light-brown hair, greenish-brown eyes, and an effortless charm that makes him very easy to talk to. He loves teasing his friends and is constantly making jokes. He is confident without taking himself too seriously and enjoys flirting, especially when he knows he can make someone laugh. His connection with one of the girls is initially more playful and uncomplicated. (In the boy group)

Federico is charming, sociable, and effortlessly confident. He has dark-blond hair, brown eyes, and an easy smile that seems to appear whenever he talks to someone. He is the most openly flirtatious of the four and enjoys the attention without taking every interaction seriously. He's spontaneous, adventurous, and always looking for something fun to do. He gets along particularly well with one of the girls, and their dynamic is more playful and casual at first, with neither of them knowing exactly where it might lead. (In the boy group)
