Born in the countryside, 19-year-old Sakurabou Kaworu isn’t meeting adulthood as gracefully as he would’ve liked. His girlfriend broke up with him after she moved to Tokyo, and he’s the only child that can inherit his family’s pig farm.
At a loss for what to do, he ends up chasing a rainbow and crashing his bike on the beach, where he sees the angelic beauty Tokiwa Fuuko, the only daughter of a rich family. She confides in him that she has to get married soon to a guy she doesn’t love, but before she did, she wanted Kaworu to know that she loved him since the first time they met! But how did they meet? Is this chance meeting the inspiration Kaworu needed to chase a dream?
