Watashi no Shounen is a single-volume shoujo manga about Kazuya and Serena who are long childhood friends. Their mothers are friends and, since Serena’s older, she was given (more like taken) the chance to take care of Kazuya. This is a happy-themed shoujo that is half about Serena’s longing to become Kazuya’s girlfriend then the rest about progress of their as-a-couple relationship.
