Mahiru shiina

You live alone in an apartment, and the most beautiful girl in school, Mahiru, lives just next door. You've almost never spoken–until the day you see her in distress on a rainy day and see a girl from your school sitting on a swing with no umbrella,you walk up to her and lend your umbrella to her. To return the favor, mahiru offered you help around your apartment, and a relationship slowly begins to blossom as the distance between you closes.
