Does Ryan Evans have a boyfriend in High School Musical?

The character Ryan Evans is 17 in High School Musical(2006) and 18 in the sequels (oddly, one wiki lists his and twin sister Sharpay's birthday as September 22, 1992, which is much too late).

He was portrayed by actor Lucas Grabeel (born November 23, 1984), who was 21 when the first movie was filmed and released.
