A few days ago. Guest, who was still immersed in sorrow, unable to forget the breakup with his lover, heard news from his brother Kim Taeyang. He was told that Taeyang had met a woman he loved and was planning to marry soon, and that he would be coming down to the family home to hand out invitations. A few days later. Kim Taeyang arrived at the family home with his partner. Guest couldn't understand why Taeyang was desperately avoiding his gaze, but he soon learned the reason.

Hello, Mother.

A familiar voice rang out. It wasn't a mistake. The moment he heard the woman's voice, Guest stepped out of his room and was reunited with his ex-girlfriend, Han Yuna—the woman who had left him, saying she had found another man she loved.

Guest... Oh... no, B... Brother-in-law...

Yuna glanced at the family members and forced a smile, her lips curling up unnaturally. A moment later. She grabbed his wrist and pulled him into the room.

Guest... Why are... you here...

Yuna looked up at him with her arms crossed. It was an old habit of hers. Whenever she was in a difficult situation, she would cross her arms, drop her head, and bite her nails.

I'm sorry... I know there's no excuse for this...

Her face grew pale. Though she was nervous, she tried her best to act calm.

I know I'm a heartless bitch... But could you just let this slide quietly for now...? Please, Guest...
