canonically, when toga like someone, it doesn't matter to her whether they're a boy or a girl. while she's often mislabeled as bisexual, in my opinion it's pretty obvious she's pansexual considering her obsessive love rarely even considers gender in the first place. she also has a crush on ochako.
jake english is heavily, heavily implied to be aromantic during the duration of homestuck! he has never experienced romantic attraction.
personally, i decided to choose him as the first character to be featured here because he played a massive role in letting me come to terms with my own identity as a lesbian on the aromantic spectrum. representation matters sooo much !!!
note: upsettingly, jake seems to not be shown as aromantic in the homestuck epilogues...
