In literature the term "restrained" serves a dual purpose, capturing both the internal struggle of emotion and the external imposition of control. Authors employ it to illustrate characters who consciously hold back their feelings—whether it is the suppression of anger or laughter in delicate, high-stakes moments [1, 2, 3, 4]—or to denote physical or societal limitations that curb human action [5, 6, 7]. This careful management of passion versus propriety enriches narrative tension and depth, as characters navigate a landscape where personal impulses are often in conflict with the expectations and constraints imposed on them [8, 9, 10].
