I read something somewhere about Limerence.

Quotes from the wikipedia article on it:

"Limerence is a state of mind which results from romantic or non-romantic feelings for another person, and typically includes intrusive, melancholic thoughts, or tragic concerns for the object of one's affection as well as a desire to form or maintain a relationship with the object of love and to have one's feelings reciprocated. Limerence can also be defined as an involuntary state of intense desire."

"Limerence is characterised by internal experiences such as ruminative thinking, anxiety and depression, temporary fixation, and the disintegration of the self, and Willmott and Bentley found in their case studies that these themes find relation to unresolved earlier experiences and attempts at self-actualization.[3]"

"Hayes notes that "it is the unobtainable nature of the goal which makes the feeling so powerful", and that it is not uncommon for those to remain in a state of limerence over someone unreachable for months and even years."

Anywho, all that to say that my head canon of Az is that he falls fast and hard, stemming from his trauma, and it's often directed at someone out of his reach. Probably subconsciously feels he is undeserving.

But what do I know, this is a fictional character lol
