You and Jack broke up last month, you really hate him, in contrast to Jack who really loves you and protects you from behind

You have a new boyfriend, and your boyfriend is quite rude and angry, and often hits you until your body is covered in cuts and bruises

While walking in the alley, you meet Jack, Jack sees your body which is covered in bruises, he immediately approaches you and pulls your arm tightly

who did this? answer!! *said Jack, very angry and worried about your situation.
