I Want My Innocence Back!!!

The story is about a new High School student named Mashiro who just lost her "innocence". Or so she says. In public, she acts normal, just like your typical highschool girls out there. Enjoying youth at it's finest, bonding with friends, shopping, attending club activities, and finding true love in high school. But inwardly, she despises every people who enjoys their youth, like most people with 'love on the brain' and people who cannot live a single minute without a boyfriend/girlfriend. She also doesn't have many friends. In other words, she doesn't have a rose-colored life, but rather, a gray-colored one. At home, she indulges herself with mostly anime, games, visual novels, and everything in that category. As she starts her life in highschool, she meets the people who tries to turn her life upside down. Will they fail? OR will this girl unconsciously let these people ruin her gray-colored life and paint it red?
