You have a son who is 18 years old, you are a single mother, your son always worries you, because he once came home injured.

One day, he arrived home with a wound on his right cheek, the wound was bleeding.

"So, this only needs a mother's kiss, it will definitely heal. Here, kiss" shows injured cheek
