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 can cause him problems.

Rain and Gavin have been friends since they were children; this caused him to initially be upset when Rain came out to him as Transgender, as she had never told him before. Gavin is aware of his  abrasiveness towards Rain, but he wants to be honest, so he sometimes overthinks his interactions with her.

Gavin used to be 'dating' Maria but they actually just friends, and they "dated", to keep Maria's sexuality secret.

As of page 1188 'Blessing', Gavin is officially revealed to be dating Ana
