Ever since the emergence of gravure idols, the practice of "pillow business" has existed. Its history runs deep, back to an era when it was commonplace for producers and corporate sponsors to maintain intimate relationships with shapely gravure idols. This trend continues today, and T-chan is said to have entered the world of pillow business for reasons involving money, her family, or even herself. Known for her flawless skin, she gained popularity at handshake events and other fan interactions involving physical contact. She continued building her presence on YouTube, expanding into beauty content, variety shows, and candid personal confessions, steadily growing her subscriber base. She also starred in numerous beauty-related online commercials, solidifying her status among industry power players. Behind the scenes of her photobook release event, she ended up engaging in pillow business in a softcore porn-style setting. Despite her youth—still considered a newcomer—her background and the stark contrast between her public image and private actions create an intensely erotic appeal. The rough, almost casual way she's sometimes treated only heightens the allure, making the contrast even more enticing.
