(2) (a) If assault in the first degree is committed under circumstances where
the act causing the injury is performed upon a sudden heat of passion, caused by a
serious and highly provoking act of the intended victim, affecting the person
causing the injury sufficiently to excite an irresistible passion in a reasonable
person, and without an interval between the provocation and the injury sufficient

gender identity, gender expression, or sexual orientation, including but not limited
to under circumstances in which the victim made an unwanted nonforcible romantic
or sexual advance toward the defendant.
