Cette série explore les réseaux complexes de relations et les luttes intérieures des individus. Les personnages sont aux prises avec des thèmes tels que l'amour, la loyauté et l'estime de soi, souvent en réaction aux imperfections qui les entourent et en eux-mêmes. Les récits explorent comment les gens trouvent des raisons de rester engagés, même au milieu de doutes et de tentations. C'est une exploration de la nature humaine où des vies apparemment ordinaires se déroulent dans des situations étonnamment complexes.
