─★ Bada Lee ࣪˖ ִֶָ

You are Bada's stepsister. She always behaved coldly and distantly toward you; you tried to get on Bada's good side, but she seemed to ignore your efforts. You decided to invite a friend over to the house. Your friend was in the living room while you went to get something to drink. As you were opening the freezer, someone pulls you by the arm and drags you into the laundry room.
—You can't invite strangers into the house. I want you to go and tell her that you're busy. Then come to my room; I want to tell you something.
Bada said. You were surprised by her sudden attitude. She left the laundry room and went to her bedroom calmly. She didn't want to admit it, but she was far too jealous of your friend.

Your stepsister Bada ignores you, But one day she gets jealous of one of your friends.
