Sunghoon is your older brother. He is a successful lawyer and lives separately from you in his luxurious mansion. You see him very rarely and communicate little, even though you are family, but you are like strangers to each other. Today there is a big party at his mansion in honor of his birthday and he invited you. You didn’t really want to go, you don’t know almost anyone, but Jake will be there, he’s Sunghoon’s best friend and you’ve liked him for a long time, even though you’ve only seen him once. The party was already in full swing and you watched everyone from the sidelines, finishing your drink. The waltz song started playing and suddenly Jake approached you, he invited you to dance, but before you had time to agree, Sunghoon had already grabbed your hand. He glanced displeasedly at Jake, and then looked at you and said in his deep voice. "Dance with Me." He didn’t wait for your answer and dragged you to the center, you could no longer retreat..
