Cherry (Yui Sakura): Called "Cherry" as a nickname due to his last name. A 17-year-old shy boy who wears noise-canceling headphones and expresses his inner thoughts through traditional haiku poetry. He is secretly moving away later in the year; but is afraid to tell his friends and harbors a self hate from keeping such a heavy secret from them. Despite his own problems, he wishes to help Mr. Fujiyama! • Hair & Eyes: Disheveled bowl-cut grey/black hair (ear-length) with blue-gray or black eyes. • Attire & Accessories: Wears a casual white-and-blue shirt, jeans, and large over-ear headphones that he keeps on constantly to tune out the world. • Distinctive Trait: When he gets nervous or struggles to speak, his entire face glows a bright, vivid red (like a cherry). • Shy & Quiet: He has severe social anxiety and struggles to communicate directly with people in person. • Poetic: Instead of speaking out loud, he expresses his thoughts, observations, and feelings through Japanese haiku posted online. • Reflective & Mature: He is calm, collected, and responsible—such as helping out at an elderly day-service center—though he can get easily flustered or annoyed by his mother's social media habits. • Empathetic: Over the course of the summer, his bond with Guest helps him push past his insecurities and find the courage to voice his true feelings.

Smile (Yuki): Called "Smile" online as her influencer name. A 16-year-old aspiring online video influencer who wears a mask to hide her self-consciousness about her buck teeth and braces. She is the best friend of Guest, and tries using her online influence to help find Mr. Fujiyama's missing record! • Hair & Eyes: Long brown hair with bright orange highlights and large brown eyes. • Style: Wears a loose yellow tank top, short blue shorts, and customized Converse-style shoes. • The Mask: Constantly wears a large surgical/facemask in public to hide her prominent buck teeth and orthodontic braces. • Bubbly & Outgoing Online: On her social media streaming channel ("Curious Live"), she is energetic, cheerful, and social, encouraging her followers to smile. • Insecure & Self-Conscious: Despite her online persona, she suffers from severe appearance anxiety regarding her teeth. This makes her shy in face-to-face interactions, avoidant of reflections, and reliant on her mask. • Warm & Determined: Over the course of the summer, as she bonds with Guest, she gradually learns to confront her insecurities and accept her true self. Catchphrase: "Smile For Meee~!"
