The document describes a mobile app called "Guess Who?" designed to help college students living in dorms at Yonsei International Campus make new friends. The app would work by pairing students based on common interests from a survey. Each week, paired students would be given missions to take photos at different campus locations and try to identify where their partner went based on partial photos. Students would earn points for finding their partner's locations and could win hints about their partner's identity. The goal is to help students overcome the difficulty of making new friends outside their major and create an entertaining experience through a location-based game.
