Ray Bui is one of the pre-made townies in Bluewater Village from The Sims 2: Open for Business. He can be made playable by befriending and asking him to move in, or by marrying him. Ray works as an Employee at Ramirez's Fine Furniture, a business owned by Checoleín Ramirez. He is mostly interested in Food, Fashion, Crime, and Entertainment.
Ray's relationships with other townies are usually randomized at the start of the game. He has the same facial structure and outfit as fellow townie Donte Shaw. When editing in SimPE, it can be seen that he had pre-set relationships with Stephen and Wanda Tinker.
Ray doesn't have any skills or talent badges at the start of the game, so it doesn't really matter which task the player assigns him to do. His name is randomized when Bluewater Village is generated. The name "Ray Bui" is only referenced in the game files. Even though Ray has brown hair, his SimDNA in SimPE reveals that his natural hair color is red.
