Campus Flower Guard

This is a story about a high school boy named Ji Tian Wu. One day he finds a fountain pen in a bird's nest. Somehow it gets absorbed into his hand and a computer like voice begins analysing things around him and he learns that he earns points in some mysterious system. Each use consumes a certain amount, which apparently he needs to keep replenishing in order to use. So far he has learned that he can earn them by coming in contact with girls.
