When Tomoyo is elected Student Council President, her dream to save the school's cherry blossom trees from being cut down begins to come to fruition. However, her never-ending duties and bad rumors about their relationship spread by fellow students due to Tomoya's reputation as a delinquent create a rift between the two. As Tomoya watches Tomoyo rise higher and higher into the distance, their relationship is stretched to the limit by a society that threatens to break them apart.
