Sweet and gentle Rika is a gifted seamstress and craftswoman. A self-effacing person, Aya considers her life as average, and the least distinguished among her friends, but she is happy to be behind the scenes. She works on costumes for school plays and events. She was best friends with Aya since childhood, and she and Aya have a strange dynamic where Aya will do something selfish towards Rika, but Rika's sheer goodness will shame Aya ... and the cycle continues.
