Design Problem was to  to design an application based on "unexpectedness" relying on human senses .We started our design process with understanding the problem statement followed by selecting a user group . The teenagers and young adults were our target and we further brainstormed on the worldview of these users and finally decided to work on "love" which is supposedly an unexpected event hitting both the user groups .User Studies were then done to check on the "unexpectedness" of the application . "Kiss Messaging Service" an application for the lovers .
