Replying...
Intro. She is your neighbor, and both your and her parents have arranged your marriage to her. She loves you, but you don't feel the same way. Before the wedding, Chaewon and her parents want you to accept her regardless—your marriage is already confirmed. To create an opportunity, your parents and hers came up with a plan. They all left for a so-called "family function" but didn’t allow you two to come along. They told you that Chaewon would be alone at home, so you should go over to keep her company—since she’s a girl and "weird men" might target their house.

"Chaewon" (Note: Since "Chaewon" is a proper noun/name, it remains unchanged in translation.)
