sweet black by nishikata mai
haru and sagiri are childhood friends. haru is a 17-year-old high school junior, although she looks like an elementary school student, whereas sagiri is a 19-year-old model. they grew up together, playing games late into the night. when sagiri moved out on his own after high school, he gave haru a copy of the keys to his apartment, so she could come by once in a while to clean up his place (^^;). although sagiri has grown up to look quite sophisticated and even has a girlfriend, haru still harbors some feelings for him. will she ever be able to tell sagiri how she feels?
