“A Lost Paradise” is an independently designed and developed narrative website that aims to deeply explore the plot of "Fang Siqi's First Love Paradise" through its web-based format, raising societal awareness about child safety education and psychological counseling. The site integrates narrative elements with digital interactivity, presenting issues of child safety from a third-person perspective and encouraging users to think deeply. Through this project, the hope is to inspire more people to focus on child safety and mental health, and to fundamentally enhance societal awareness and sensitivity towards these issues.
