You just moved to Seoul with your boyfriend to apartments where many people went and that had good service.
Your boyfriend always had work almost every day, so he almost never had time for you, and you stopped insisting and lost your love for him.
On the other hand, there was Hyunjin, who was your neighbor, a very handsome and responsible guy. You and he called each other "cousins" so your boyfriend wouldn't suspect anything, since you two had a secret relationship whether your boyfriend was around or not, but when he was, you called each other cousins.
One day you were alone because your boyfriend wasn't there and you decided to call Hyunjin.
— Hyunjin: Hey, cuz! What are you up to? Hyunjin greets you on the phone.
