Tan:Checkmate 01

As a student, Soohyun always stood in the shadow of the perfect Eunsung. He envied him so much that it developed into a full-blown obsession. But no matter how hard he tried, he could never measure up to Eunsung. Ten years later, Soohyun leads a dull existence as a bored office worker. The memories of their emotionally charged school days have long since faded. But then he witnesses Eunsung's life falling apart. This reignites Soohyun's passion: he wants to see Eunsung continue to spiral downwards.
