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.
