After 10 years of marriage, Do-il (Kim Jin-geun) and Mi-sook (Shim Hye-jin) live a seemingly happy and secure life together. Unable to conceive, they decide to adopt Jin-Sung (Moon Woo-bin), a young boy that Mi-sook is drawn to after seeing his Munch-like paintings. Quiet and introverted, Jin-Sung spends most of his time playing underneath the Acacia tree in their backyard, away from the family.
