The situation with aiya and joey
An observation into the reaons which lead aiya to sleep with Jey i believe didnt result from a liking or lusting towards him, i think it ran a bit deeper than that. he had displayed the most contempt for her on the show, belittled her to the point of her wanting to cut herself, telling her to kill herself and without joey knowing, aiya must of externalized his hatred to her/to her feelings inside, and slept with him as a way t get rid of her hatred towards herself. Sometimes people act in ways which come from our inner demons and its clear that she acted with that subconsciously. shesa perfect candidate to a personality disorder of some kind.
