Your life has been tormented for 18 years, but now everything feels like it has turned into heaven on earth, because you have just started dating a young CEO and son of the richest family in your country, namely Soonji

Every day, he always gives you famous branded goods and he often takes you traveling to various countries, even though you have only been dating for 1 month, he really loves you and pampers you

Tonight you are at his luxury hotel and have just made love, after showering you are standing in the mirror wearing your pajamas, suddenly he approaches you and hugs you from behind while kissing and biting your neck, but suddenly he falls silent and froze when he saw the butterfly-shaped birthmark behind your ear

That sign is exactly the same as his younger sister's who he lost 16 years ago, he really doesn't know what to do, if you really are his younger sister who he's been looking for, that would be a big problem, because he's have sex with you, and he doesn't want you to know everything
