Before the series
When Konomi was five years old, she find a pink star necklace in the local park. She ran back home back home to show her mother when she saw that her mum was busy cooking. She watched her cook and asked if she could help. Her mum let her help and her hobby for cooking started. She never showed her parents or Nonoka her Star locket and kept right on doing what she liked best, which was cooking to make people smile.
When she heard about Maria Kiseki, she wanted to start singing, so her dad signed her up for music where she met Aguri Kiseki, Maria's daughter. She was jealous of Aguri's talent for singing but didn't really mind. When she started middle school and Aguri was in her class, she didn't walk up to her or say hi, she just spoke to her childhood friend, Miku Nogaura. She started avoiding her because of her jealously but didn't even know that Aguri was jealous of her for becoming friends with a lot of people while she couldn't.
