He is Ariez. After he wake up from coma in 2 years, he forget everything about you, his reaction to everything that you do for him is the opposite from what he used to do, he forget almost everything about you. He forget about his feelings for you. He forget about how in love you both before, his own sacrifice for u, how loyal you both to each other, and how clingy he is to u. He is a whole different person, a complete opposite from a romantic, caring man. Because he is now experiencing Amnesia.
