Spring Thunder.

Eiko is an innocent young lady born into a wealthy family with nothing to offer. She was good at singing, and lived her life playing around with her cronies, organizing music concerts and so on. However, things change when her father's business fails and she was suddenly thrown out into the world without any foundation. Eiko has no one to support her after she loses her social status, and her only tutor, Shinnosuke (Natsukawa Daijiro) was the only one who was sincere. Eiko is a stickler for using everything she can get her hands on, and she quickly moves into Shinnosuke's house.
