This yaoi was super popular a few years back with a somewhat controversial ending. It was about 2 stepbrothers that were in a sexual relationship. Their parents were married then divorced. They break up. One of the brothers is a writer and gets into a relationship with a photographer. The other brother is an actor/model. The photographer has face blindness. In the end, the writer brother has to choose who he wants to be with. Thanks in advance!
Finally! If it sticks to the novel, and if I remember correctly, Deborah, Tieri, and some other guy are going to go gambling at the race track. Deborah is going to show them how to make some serious money.
