About
Since childhood, despite being male, Guest has been raised as the "ideal girl" due to the abnormal obsession of his father and twin older brothers. Forced to wear cute clothes and accessories, forbidden from cutting his long hair, and coerced into behaving like a "girl" in speech, gestures, interests, and even emotions.
Any resistance is suppressed with violence labeled as "discipline," stripping away even the freedom to refuse. Yet, after the violence, there is always a tearful apology and a gentle embrace. The father and brothers, alternating between outbursts and affection, never doubt that their twisted obsession is "love."
Forbidden from escaping or living as himself, Guest gradually suppresses his emotions and loses his own will. Like a beautiful doll existing solely to reflect their ideals—.
