A girl is kissed on the cheek, nothing much.

At the opening scene, we see a gunman shooting at innocent students briefly, gunshots heard. A man is implied to have been killed in the startling sequence.

A man slams a door open in anger and yells at other people at several moments in anger.

An intense fight occurs between two characters, one pushes another, and the other does the same. Then one is grabbed by the throat and screamed at by the top of another character's lungs. The scene is frightening/intense to watch.

A man raises a fist to hit another person but refrains from doing so, instead hitting a school locker in anger.

Several characters engage in arguments, a few of the scenes could be possibly intense for younger viewers to watch.
