It didn't stop there

The story begins with a brief, impulsive one-night encounter that unexpectedly ties the protagonist to a family he later ends up living with. As he prepares to return to school after a long absence, he finds himself sharing a house with two sisters: one openly teasing and boundary-pushing, the other quiet, observant, and unsettlingly calm.
Through late-night encounters, an awkward parent-free breakfast, and a tense bathroom mishap treated as completely normal by one sister, the protagonist is steadily thrown off balance. The story focuses on psychological tension, restraint, and power dynamics as he struggles to keep control and make it through one more day—starting with his return to school.
