I dont know why some people are mad with Director... We could figure out Ahn's personality...

I dont know why some people are mad with Director... We could figure out Ahn's personality because we read the story from his perspective and we know what he thought but how Director would know such thing?? He was straight, he was dating an older woman, someone approached him, he asked him to have s*x just to get rid off him but he then agreed to it, he met him again at the company and after a while they ended up having s*x again.... OF COURSE HE WOULDN'T KNOW THAT HIS FEELINGS ARE GENUINE!!!!!!
