The Munekata Sisters

Noriko is perfectly happy living at home with her widowed father, Shukichi, and has no plans to marry -- that is, until her aunt Masa convinces Shukichi that unless he marries off his 27-year-old daughter soon, she will likely remain alone for the rest of her life. When Noriko resists Masa's matchmaking, Shukichi is forced to deceive his daughter and sacrifice his own happiness to do what he believes is right.

After the death of their estranged father, 3 adult sisters invite their teenaged half-sister to live with them.

Twelve-year-old Koichi, who has been separated from his brother Ryunosuke due to his parents' divorce, hears a rumor that the new bullet trains will precipitate a wish-granting miracle when they pass each other at top speed.

Two closely-bound, emotionally wounded siblings reunite after years apart.
