I noticed this lately, even around me in real life, some people, especially guys, when they get attached to someone they feel like they have some kind of ownership over them and want to control what they do and say. It seems to me that's what happened to said individual that caused lots of drama. It went to his head that he met her and she remembered him and talked to him at RnRC concert.
If someone's fake in all of this, it's him. Not Ayu.
