Pieta in the Toilet

Both movies were written and directed by the same person, besides that on the surface they dont look like they have much in common. However, both movies discuss themes of love, both have sad elements and in both theres an age gap between the characters.

One of the best bittersweet movies I've seen. The premise is fairly the same of an artist (of a different genre) with a neurological condition meeting a young female student. In both stories the characters learn more about themselves and the true meaning of love and life.
