The return of Viola, his first love, triggers a mutual feeling, always existent, which sadly ends due to a series of misunderstandings. The love between the two is strong, even if the relationship is filled with furious quarrels. Its end comes about in an unusual way: aged and sick, feeling the onset of death, Cosimo climbs to the top of a large walnut tree and hangs himself on a passing balloon. Thus, without betraying his promise to never set foot on the earth again, he disappears into the sky, without even giving the earth his remains.
