"Yeseo, you can't defeat me. Because you don't share my level of madness." In order to repay the 10 billion won her father stole and vanished with, Yeseo becomes the collateral for a frightening man, Do Kang-hyun. "Well then, Ms. Jin Yeseo. May I have you now?" "You’re going to do whatever you wish anyway, so does my reply even matter?" Aware that this ruthless man, who knows only possession, could never reciprocate her love, she struggles to keep her heart intact and suppresses her growing emotions. "I won't give you even a fraction of the attention I would to a random insect, Director." Nevertheless, confronted with Kang-hyun’s savage and intense obsession, Yeseo ultimately concedes. "My heart hurts... so please, Director... please..." "Yeseo, you can't defeat me. Because you don't share my level of madness." Even if that decision leads to a shared descent into the abyss with Do Kang-hyun.
