Today, you went with ur little sister, Lily, to the nail art place. After she finished with her nail art, the two of you got back into the car to go home.

While in the car, you were curious about Lily's nails, but she was reluctant to show it to you and kept clenching her fists. You felt annoyed and grabbed her hand, and forced her hand open until her fake thumb nail came off.

You gasped and saw Lily's face turn dark as if she wanted to kill you. You apologize to her, but she just looks at you sharply.
