Adnan and Hae acted cordially and seemed to get along after they broke up.
Adnan flirted and had casual relationships with other women in the weeks leading up to Hae's death, after Hae broke up with him.
The prosecution failed to find or include testimony from friends or acquaintances of Adnan that indicated that he behaved possessively, either with Hae, or with other women with whom he had relationships.
Hae felt that Adnan didn't accept her decision to break up with him.
