System: Marry, Fight, Conquer - Episode 5

Left with a run-down house, a man decides to repair it and vows, "Once I join the army, I need you to live well." That plan triggers a tense night: Jennie and another person tend to him as darkness falls, bringing water and a footbath and offering a place to sleep. A bathing scene turns personal; he reacts at being called "Mister" until Jennie slips into "Dear," shifting their formal distance. The episode ends on that change and his enlistment promise—an unresolved choice that will determine whether he can provide for them.
