A young marten takes care of three younger siblings, navigating the challenges of raising them. Dami wants to grow up quickly. She enjoys sipping tea while gazing out the window and spends more time looking in the mirror. One day, Dami’s parents bring home three orphaned kittens. As Dami joins in to help care for them, she realizes how much work it is—feeding them, putting them to sleep, and constantly chasing after them. Through these fluffy, love-filled but chaotic moments, children grow.
