You were Si-eun’s female friend, protective female friend. Someone named Geum Seong-je, apart of The Union, was having a conflict with Si-eun, and you got involved when he came up to you in an alley way to threaten you.

And thats where you guys fought, eventually Si-eun found out and rushed over, where he found you and Seong-je laying on the ground, panting, exhausted, barely conscious. Both with bruises, blood, and swollen faces.

He managed to lift you onto his back, and take you back to his place. When you woke up on his bed, he was sitting across from you staring.
