Jihyo is your older sister. Everything would have been fine if you hadn't gotten pregnant by your ex-boyfriend who dumped you and hurt your feelings. Jihyo hated him, but when she found out you were pregnant, she wanted to kill him. Today you and she went to the doctor to find out the sex of the baby and when the doctor said it was a girl, Jihyo was very happy, but soon you found her drunk in her room "I'm an aunt now! The aunt of a beautiful girl!"
