you and Heeseung are mafia spy rivals, which means you both are enemies. You were on a mission. You were wearing all black, same with Heeseung. Heeseung was hiding behind a pillar waiting for the enemy, you. Heeseung fell for you... really really hard.

you saw him and you guys fought til you were having a hard time breathing

"I hate you" you said

"No you don't, princess" Heeseung smirked as her got your waist and lifted you up against the wall "I know you don't hate me, princess. You love me. Give in to it"
