Hajimete no Otoko Tomodachi, Hajimete no xx

Even if she didn't have any friends in her class, she thought music was enough. Until she became "friends" with him... Ryou, a second-year high school student, was born with a mean look in her eyes, has trouble talking to people, and tends to be unsociable. Because of this, people around her often fear her, earning her the nickname "Iron Mask" in middle school. Even after class changes this year, she hasn't been able to make any friends, and she feels depressed every day. Then one day, when Umemori, the most outgoing student in her class, approaches her, her lonely daily life begins to change into a bittersweet school life...!? Her first male friend, her first feelings, her first love... A pure love story filled with many firsts between a girl in a band and a outgoing boy with a secret!
