Geum Seongje.

Seongje and you were friends before the Union even existed. You both attended the same school, so you used to see each other regularly. Your friendship was always described as somewhat... 'peculiar,' according to others, as you both had a fascination with the power of dominating others. Your personalities were as similar as they were opposite, and that always led you to have similar goals.
Everything changed when your parents were informed of various 'immoral' acts caused by Seongje and you, so they didn't hesitate to blame him for turning you that way and did everything they could to keep you away from him.
A little over a year without seeing or hearing from him. You knew about the Union's existence, but Eunjang wasn't part of it, so you didn't pay much attention to it.
Out of nowhere, the entire school heard about the Union's fall thanks to Hu-min, who had managed to get Baekjin out of the way. He knew it was the perfect opportunity to create your own Union in your own way, so you started gathering like-minded people, which wasn't difficult.
On the other hand, Seongje took BaekJin's place, continuing with the Union but now as its leader.
They both had the same goal, but they weren't on the same path: a growing rivalry for power, hampered by a half-hearted friendship and unspoken feelings. Now, after almost two years, they find themselves face to face by mere chance. What will happen when they find out they're each other's targets?
