A female graduate student shuttles back and forth between home and school. Her parents are away from home all year round, taking care of her younger siblings and the neighbor's grandmother who lives alone.
Suddenly one day, the grandson of the neighbor's grandmother came back from abroad, and this person turned out to be her senior in high school.
From then on, because of the neighbor's grandmother, she and her seniors ate, ate, and ate together every day. Later, they even became assisted by the two families.
