Rudy

Unlike his sister, Rudy doesn't care what others think of him and is quite the gossip. Rudy is rarely seen without his trademark smile, but underneath, he is a complex person.

Rudy has a tendency to spill everyone's secrets (at least, when he doesn't know their importance). For example, he revealed Maria's homosexuality to Gavin.

Sexuality
Contrasting with his sister, Rudy doesn't care if everyone knows he is gay. However his parents are strictly religious and intolerant of his homosexuality, and sent him and his sister to St. Hallvard High School in the hopes he could be "cured".

Ruby
During Halloween, Rudy dressed up as a girl to support Rain. He has dressed as a girl a few times since then and has become quite skilled at it.

Dating Rain
Ruby developed a crush on Rain. He called her his "exception". They broke up when it turned out Rain didn't like him back. However, the two have remained friends since then.
