Xavier didn't expect this to happen. He went to the bar to relax and observe people. Also, he's planning to forget Athena. He's been restless too for more than five years. He took physical courses and then, mental courses. He finished his thesis and working for another Ph.D. He wanted to forget her badly because it wasn't healthy to keep thinking of her and not be able to do it with another woman.
He tried looking around and checking out a female body but no one is attractive to him. It's all Athena. Athena there and Athena here. He never got laid for more than five years. The day that he promised Athena to court her after five years, he never got a chance to do it with another.
