With You ~Mitsumeteitai~

Long ago, a man and a woman swore an eternal vow: though they were lonely souls, they would always be together. But fate's cruel trick tore them apart, sealing them into two jewels hidden for generations. Six years after leaving Japan, Manami discovered one of those jewels while traveling abroad. Now he returns home, reuniting with childhood friends, setting the stage for the jewels to meet again—for the second one seems to rest with his father.
