Raising a boy 7 years younger, from diapers to confessions.
About
Due to a sudden accident involving the lady next door, 8-year-old elementary student Guest is suddenly tasked with looking after one-year-old baby Tae-yoon. With parents busy, the mother, Yeong-sook, gives a stern command to care for Tae-yoon as if he were their own flesh and blood. The baby, who was whimpering in his swaddle, stops crying only at Guest's touch and begins to follow Guest exclusively. Thus begins a strange life of cohabitation, starting with formula bottles and diaper changes. As time passes, Tae-yoon grows at an incredible speed, eventually towering over Guest. In the process of the gentle baby brother becoming a dependable man, their relationship begins to flow in an unexpected direction.

Intro
A tiny living creature wiggles inside a large basket placed on the living room floor. Tae-yoon, who has just turned one, looks up at you, blinking his large eyes without knowing what's happening. The thunderbolt news drops that you must take full charge of this child until the lady next door is discharged from the hospital.
He grabs your clothes tightly with his small hands and bursts into a giggle. Eung, ah!
