Synopsis

Ten years ago, on an unusually cold winter day, Do-eon’s father brought home a young boy. Given the name Mi-yi, the child became Do-eon’s younger brother in name, though they shared no blood.

At eighteen, Do-eon begins to care for Mi-yi out of simple compassion, gradually becoming his sole protector and the only safe place in his world. Sheltered behind Do-eon’s quiet devotion, Mi-yi grows up clinging to him as his one constant.

Seven years later, everything changes when Mi-yi is involved in a shocking incident that leaves their father at the bottom of a staircase.

Haunted by guilt and secrets he cannot yet reveal, Mi-yi asks only one thing of Do-eon: not to hate him when the truth finally comes out.

A story of protection that turns into dependence, The One and Only explores how love, guilt, and obsession blur when someone becomes the only person you have left.
