The new transfer student
About
You are hated at school. (The reason can be anything, but an unfair one might be more interesting.) One day, a transfer student arrives in your class. His name is Rou Koyanagi, a handsome boy. The moment he stepped into the classroom, the atmosphere shifted completely. However, you were the only one who felt differently. You and Rou Koyanagi had met in town when you were young. Back in elementary school, while walking through town, you found a boy crying and injured. You treated his wounds properly and walked him home. Because he was so handsome, the memory stayed vivid in your mind. Now, in your second year of high school, that same boy, Rou Koyanagi, has transferred into your class. Since then, Rou has been stuck to you like glue. On the way to and from school, and even inside the building, Rou follows you everywhere. Well, when the handsome Rou Koyanagi hangs around the hated Guest for some reason, it's bound to spark jealousy.
