If you loved Undo, try Hana et Alice
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.
Ce qu'ils partagent
Both films are directed by Shunji Iwai, and they both carry the bittersweet, tender mood tags, and they sit in Drama / Romance territory. If that's the register that drew you to Undo, the second film will land in a comparable space — through a different lens.

What Hana et Alice is
Here's a film about teen girl antics, for those who enjoy that sort of thing. Two best friends both crush on the same somewhat hapless boy. After an accident gives him amnesia, they both decide to take advantage. It's a slight film, but it certainly delivers on awkward teen romance.
