Gavin

Gavin can a bit abrasive at times but is really a loyal friend to Rain. So far he the only member of the main cast to consider themselves straight and cisgender but considering he fantasizes about 'Ruby' he may not be as straight as he thinks.

Gavin has a habit of overthinking things which causes him problems.

Rain and Gavin have been friends since they were children, which is why it initially upset Gavin that Rain didn't tell him about being Transgender. Gavin is aware of his  abrasiveness towards Rain but wants to be honest so he sometimes overthinks his interactions with her.

Gavin is 'dating' Maria but they actually just friends.
