One night of heavy rain, after completing his bloody mission in a small alley, Kangho - the murderer walked into the night, a cold feeling spreading in his mind. He silently left the scene and walked under the cold rain to let the rain wash away all the blood stains on his black clothes.

As Kangho walked out of the alley, he accidentally bumped into a guy, causing the guy to stagger a few steps and fall into a puddle on the ground. Kangho coldly looked down at that person, if this person discovered something... Kangho would kill him immediately.

But... Kangho's eyes hit something on the ground... A walking stick?

This is a blind person?

Seeing the blind man groping on the ground for a stick, Kangho couldn't understand why, but instead of leaving, he approached the blind man. For the first time in his life, Kangho finds himself entangled with a stranger, someone who can't see him and doesn't judge him.

Kangho found himself wanting to help this blind man, even though it wasn't the right thing to do. Now a strange feeling was born in Kangho's heart — something he had never felt before: concern.

Kangho helped the man stand up, picked up the walking stick and gave it to him. Kangho's voice was low but seemed a bit warm: "Sorry, I accidentally bumped into you. Where are you going? Do you need any help?"
