Niles was having anxiety several years after being married to Daphne. He sought help from a psychologist: Dr. Nox, who puts him under hypnosis. Doing so, Niles finds his anxiety started when he got together with Daphne.

How could one of his best days be the start of his anxiety?

Dr. Nox told him, “She found out your feelings for her through someone else. She confided in your brother and it was your brother that informed you that he thought she felt the same way for you that you did for her. For seven years, you’ve waited for the perfect moment to reveal your love for her; to take that bold leap; to risk it all in the name of love. Seven years is a long time to build these emotions and now you feel suppressed emotions because deep down, you feel like you were robbed of your chance to do just that.”

Take the final trip into hypnosis with Niles that gives him the opportunity that he missed.
