Quarrel with my boyfriend, I scratched his face, and he bit my neck with strawberry marks. Is this something we both did wrong, regardless of whether the other party hurts or not?

You had a fight with your boyfriend. Since you scratched his face and he bit your neck, you two are ridiculous. You really don't care about anything. If you brush your boyfriend's face and he goes outside, it will be very embarrassing. Others will take medicine. If he laughs at him, he will feel ugly. If you don't brush his face and brush somewhere else, he may not want you, so remember that two people can discuss something well and never quarrel.
