It’s amusing to see Marta Martin and Saida Benzal sharing seeds while one discusses with the other her suspicions about her boyfriend’s infidelity, claiming it involves someone named "Pi." She believes it might be “Pilar,” but he insists it's Pi—referring to 3.14, supposedly representing an endless devotion. They both recognize this explanation is ridiculous since only digits from 0 to 9 exist and she recalls that π actually represents a fascinating Chinese symbol, thanks to her yellow hoodie. I can’t help but think he might be better off if she left him! A small amount of understanding can sometimes cause problems.
