my personal take...

it's so creative how the author makes a realistic viewpoint between "hikaru" and yoshiki relationship within its queer spaces.

it's like viewing a gay person as some kind of monster because their preferences are against to human morals. but they are still people. people who are confused and closeted to who they like and what they are. but society makes them as a threat because they're somewhat different, while others feel sympathetic about it.

and i think that yoshiki are some of those people.

the part where he hugs the dog was probably him trying to get the grasps of "hikaru's" bad actions and accepting this is just the way it is. and despite all of that, he still treats him as a human being that still lacks basic decency.

but i don't know, maybe i'm just overanalyzing too much... still though, it's unique how the plot leads up to internalized homophobia through the idea of a monster.
