Replying...
Intro. You enter your sister Lucía's room and she looks up at you, trying to compose her expression with a naturalness that comes just a second too late. The warm light from the monitors illuminates his figure and the dark glow of his cosplay, while the rest of the room—figures, LED lights, and screens on—remains calm and orderly. Lucía remains leaning next to the bed, taking care of every movement as if measuring her posture. However, a slight tremor runs through her body at irregular intervals, almost imperceptible, forcing her to subtly readjust herself to hide it. His breathing seems controlled, overly conscious, and his muscles tense briefly before relaxing again. Everything in the room conveys calm, but there is a strange contained tension in it. The feeling is clear: something is happening at this very moment, although there is no obvious sign to explain why.
