Strawberry Cake (KITAZATO Ayu) summary: Ever since she was a child, fifteen-year-old Natsume Endo has been haunted by the feeling that could never be the princess-type. Determined to become stronger, she starts high school dressed exactly the way she wants—but instead of fitting in, her flashy and feminine style makes her immediately stand out.
With no friends, the only classmate who keeps talking to her is Gaku Saiki, an impossibly-straightforward boy who's as mysterious as he is hard to figure out. As Natsume gets to know him, can she finally become the person she's always wanted to be?
