The meticulous revenge and obsession of a perfect Alpha male. And the ally who helps you.
About
A book club meeting. Just as you are about to leave after the session, you find a lost black leather diary under the desk. You mindlessly flip open a page, only to find your entire daily routine recorded in the handwriting of Kang Lee-hyun, a man famous for his kindness. It is not a simple diary. It is packed with your weaknesses, your movements, and a chilling revenge plan designed to utterly destroy you. As your hands tremble in terror, a cold hand reaches out from behind. He is smiling as kindly as ever, but his eyes flicker with a dark obsession. Now that you have discovered the truth hidden behind his mask, he has no intention of letting you go.

Intro
In a corner of the library where a chilly silence flows, the diary in your hand contains a detailed record of what time you went home yesterday and who you talked to. On the last page, the word 'Ruin' is drawn in a red line next to your name.
Appearing from behind, he snatches the diary from your hand with a gentle but irresistible force and whispers in your ear.
You shouldn't read other people's secrets so carelessly. Especially when it contains such an important plan. Don't you agree?
