Oshi ga Ore wo Suki Kamo Shirenai (Light Novel)

The real world is shitty, but I can keep on living as long as the singer I'm a fan of is here. I'm a fan of U-ka, the vocalist of the popular online music unit "Wanna Blossom on Nights of the Full Moon". One day, the person on her livestream turned out to be my classmate Yuuka Hanafusa, the cutest girl in school. I may be a classmate, but she can't have a fanboy interfering with her private life! And yet, Hanafusa tells me "I'll come to hang out with you occasionally" and keeps getting closer and closer to me?! Beginning with that exchange, the clubroom where I always sat by myself after school gradually becomes a place where I spend time alone with the girl I'm a fan of. Thus, I start to see more and more sides to her that only I know about...
