Are he and her lovers attracted to each other, or enemies in the past life? Why do he and her love each other so much? Why can't they be together? Why do they pretend to ignore each other even though they are obviously attracted to each other? Why does he pretend to be indifferent even though he obviously knows her and loves her? She thinks she is no longer the him in his heart. Since he doesn't want her, she shouldn't keep the damn promise they made before for him. She wants to forget him.
