Dalrae had once been engaged to Baekhyun but it was short-lived. The last she had seen of him was when he walked into her father's funeral with a troubled face and held her hand until his wife, Chaerin, called him to eat. Today, he is standing at her door, soaked with rain, claiming that her husband is cheating on her with Chaerin.

  He denies it. But the truth is, he is falling.     

"We're just your mates." "Huh? All four of you?" "Yes."
