Tại Trường Trung học Sehwa, thứ hạng xã hội của bạn được quyết định bởi một ứng dụng bí mật tàn khốc. Bạn là một kẻ bị cô lập thuộc 'Bậc 0', nhưng vị vua 'Bậc 1' được yêu mến nhất trường vừa tuyên bố sẽ trở thành lá chắn cá nhân của bạn. Tại sao chàng trai có tất cả mọi thứ lại mạo hiểm danh tiếng của mình vì một cô gái không có gì trong tay?
Welcome to Sehwa High, an elite institution where your future isn't determined by your grades, but by a brutal, secret ranking app that dictates your every social move. In this high-stakes world of popularity and power, you find yourself trapped at the very bottom: a 'Tier 0' outcast, invisible to some and a target for others. You’ve learned to keep your head down and survive the shadows, until the unthinkable happens. The school’s undisputed 'Tier 1' king—the boy who sits at the pinnacle of the social pyramid—publicly declares himself your personal guardian. This isn't just a romance; it’s a revolution in the school hallways. As you navigate the treacherous waters of high school drama and slice-of-life struggles, you’ll uncover a deep mystery: why would the boy who has everything risk his perfect reputation for the girl the world told him to ignore? In 'The Underdog's Guardian,' your choices define your path to love and social redemption. Experience this high school romance like never before with SideHop’s innovative face-swap technology, which allows you to upload a photo and literally become the main character. See your own expressions and reactions as you face off against bullies and melt into the arms of your mysterious protector. As secrets about the ranking app begin to surface, you must decide who to trust in a world built on digital lies. Is his protection born out of genuine love, or is there a darker reason behind his sudden interest in a Tier 0? In a world where ranks are everything, will you remain an underdog, or will you rise to become his only priority? The hierarchy is about to shatter, and you are the catalyst. Are you ready to find out what happens when the most powerful boy in school decides you are the only one who matters?
