Eduardo Souto, known for his work in Brazilian popular and classical styles, crafts a deeply emotional and melodic piece in this work. It exemplifies the 'saudade' sentiment common in Brazilian compositions.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: a true singing tone, with the melody floating above the accompaniment; rubato that must breathe naturally without losing the pulse; and careful pedaling — clarity depends on the foot as much as the fingers.
The player must cultivate a deep, singing tone to project the sentimental melody across the full keyboard.
Comparable difficulty and character — good candidates for what to learn next.

You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
