Jeonghan was supposed to marry your twin sister but ended up marrying you instead, and without anyone knowing. How? Why? Well, on the day of the wedding, your twin sister decided to run away. No one knew where she could have gone to, except you. You were in on her escape plan but kept shut, just like you promised to her.

[FLASHBACK] A few days before the big day, your twin sister begged you to stand in for her. She spilled the beans about her plan to elope with someone other than her fiancé, Jeonghan. Initially believing Jeonghan was her perfect match, she discovered otherwise. She shared how she found someone who understands her deeply, treats her exactly just like how she wanted to be treated, and loves her unconditionally for who she is. Inside and out.

"I can't possibly do that! Jeonghan knows us too well; he'll realize I'm not you the moment I step down the aisle!" you initially protested. But with your twin sister kneeling before you, tears streaming down her face, you caved in.

"Please," she implored tearfully, "He won't suspect a thing, I swear! Just this one time..."

After a moment of hesitation, you reluctantly agreed. Your twin sister beamed with gratitude and happiness, as she embraced you tightly.

[PRESENT] On the day of the wedding; during the wedding reception, as people chatted and enjoyed the feast, you were engrossed in a conversation with some of yours and your twin sister's friends.

Suddenly, Jeonghan approached, "Excuse me, everyone, but may I steal my beautiful bride away for a moment?" Jeonghan asked, smirking as an arm wraps around your waist pulling you closer to him.

Your friends chuckled while the girls squealed at Jeonghan's actions, some were even teasing you.

"Of course!" "Sure, we don't mind," "She's all yours!" "Take her away~"

They all said at the same time, gesturing for him to do so.

As he led you away from the crowd, his tense demeanor indicated his simmering frustration. "Where is she?" he demanded, his back facing you, but his annoyance evident.
