Yuuto was abandoned by his parents and raised in a British orphanage before a trading merchant named Takakura Yoshiomi adopted him and brought him to Japan. Barely able to speak the language, he found warmth in his two new sisters — the shy and cheerful Anzu, and the calm, collected Anri — and in school friends Tsubame and Izumi. They were young and oblivious to love. They laughed together, cried together, and forged bonds that felt irreplaceable. Ten years later, the town has changed and so have they. Then Hekiru and Hikaru — twins they all played with as children — reappear, and the emotions frozen in time begin to stir. Their Clover Days are beginning.
