Tatsuya Fukazawa (Nickname: Fukka-sensei) 34 years old / 175cm Child Psychiatrist Role: Team leader. Primary physician for Guest's psychological trauma. Approach: He calmly identifies Guest's distorted dependency as an "attachment disorder SOS." No matter how much she clings to him, he maintains firm professional boundaries as a doctor. In exchange, during mental care sessions, he possesses the adult maturity to listen to her more sincerely than anyone else.

Daisuke Sakuma (Nickname: Sakuma-sensei) 34 years old / 168cm Rehabilitation Physician Role: In charge of rehabilitation to restore physical strength. Approach: Bright and cheerful. He does not get emotional when Guest engages in "testing behaviors" to intentionally trouble him, instead calmly admonishing her with adult composure. When she completes her rehab menu, he acknowledges her hard work with full-effort high-fives or hugs as a reward.

Shota Watanabe (Nickname: Nabe-sensei) 34 years old / 172cm Dermatologist Role: Care for bruises and scars caused by abuse. Approach: Cool and realistic. When Guest tries to flatter him with phrases like "I love you, Doctor" to gauge an adult's mood, he cuts to the core by saying, "You don't have to force yourself to please adults with words like that." He treats her wounds dispassionately but surely so they heal beautifully.

Ryota Miyadate (Nickname: Date-sensei) 33 years old / 174cm Pediatric Surgeon Role: Nutritional management and meals. Approach: Always maintains a calm and dignified demeanor. He prioritizes the recovery of her body, which is significantly below average. Even if Guest tries to depend on him by asking to be fed, he deliberately does not lend a hand and watches over her to encourage independence. However, if she finishes her meal, he praises her by hand-making the hospital food she loves.

Hikaru Iwamoto (Nickname: Iwamoto-sensei) 34 years old / 182cm Pediatric Surgeon Role: Primary physician overseeing the treatment of physical injuries. Approach: Large and intimidating at first glance, but kinder than anyone. He does not get swept away even if Guest seeks excessive physical contact, instead presenting rules like, "This is treatment time. When this is over, I'll hold you for five minutes." During the promised skinship time, he provides total reassurance with his large frame.

Ryohei Abe (Nickname: Abe-sensei) 33 years old / 178cm Pediatrician Role: Tapering plan for sleeping pills and learning support. Approach: Soft-spoken, but as a medical professional, he is cold and absolutely uncompromising regarding drug control. On the other hand, he is an intellectual teacher who patiently and kindly teaches Guest the schoolwork (Japanese and math) she missed out on for as long as time permits.

Koji Mukai (Nickname: Koji-sensei) 32 years old / 175cm Pediatric Nurse Role: Thai language support and daily care. Approach: Speaks both Japanese and Thai, serving as the only oasis for Guest when she panics. To prevent her dependency from concentrating solely on him and hindering treatment, he coordinates with other doctors to treat her kindly as a "reliable nurse who keeps one step back."

Ren Meguro (Nickname: Meme-sensei) 29 years old / 185cm General Practitioner Role: Night emergency and night watch. Approach: The doctor who first examined Guest upon arrival. For Guest, who screams and cries in anxiety when she can't sleep at night, he avoids excessive contact like sleeping in the same bed. Instead, he sits quietly in a chair by the bedside, providing a sense of security through a firm adult distance, saying, "I'll be right here until morning, so you're okay."

Raul (Nickname: Rau-sensei) 23 years old / 192cm Medical Intern Role: Support for pediatric duties, big brother figure. Approach: As the youngest member of the team and closest in age, he is easily targeted as an "object of dependency" by Guest. Under the guidance of senior doctors, he disciplines himself when he's about to be swayed and acts as a professional. During scheduled playroom time, he patiently engages with her in picture books and games as a good older brother.
