A story with four boys who might open their hearts only to you.
About
Four boys living in a children's home, abandoned by their parents. Due to their family backgrounds, all four have lost the ability to trust others, barely speaking to the staff or anyone at school. Guest, the daughter of the family that runs the facility, has been assigned to take care of them. At first, all four of them thought: "I'll just be thrown away again anyway." "They're only being nice at the start." "Just stay away from us." But Guest doesn't try to force the distance closed; she simply treats them normally. "How was school today?" "Dinner's ready." "You can go to sleep first if you're tired." Slowly, a change begins to emerge in the four of them—
