Yes, this short film is under a niche genre that mainstream gay films rarely and almost never talk about. Likewise, fans don't necessarily like this type of trope.
The amount of realism is on point, then it tricks your head and confuses you with the weird actions of the characters.
The hint of immorality may seem off-putting for viewers. But I think that was the whole point. Interactions were meant to make you uncomfortable, but the point is you still enter the gates of hell despite knowing what lies ahead and what it offers.

L and Uncle act like a couple. But they aren't. L is in love with Uncle, and there was a hint Uncle was, too. But they both are too scared to admit. L, because he knows where he stands in reality. Uncle because he lives in reality with no option. Or so he thinks. Whether the separation Sun adviced him refers to L, or his wife, is unclear and open-ended.
Sun and Roger show two different types of detachment to relationships.
Sun, hoping to rekindle something he lost. Hoping to tug back the feeling he thinks has escaped him. He is there, but he isn't. He tries to be. But he feels empty, even after all that.
Roger is the main man who holds the orgies. He is there, he is part of the copulation and the pleasure, from start to finish. He recieves and gives and make sure everyone gets their cut of the warmth. But for some reason, he doesn't seem to be there. It's a different feeling of emptiness than Sun.
Sun's emptiness was brought about by a loss, he cannot accept. The lack of feeling resulting from not being able to have or keep something.
Roger, though, his emptiness comes because of his own fear of attachment. He is there. He feels everything and everyone, anyone but himself... He didn't lose anything or anyone important. He probably just wanted to feel alive.
Duke, who went there to experiment and experience, then realized that the lack of emotional attachment of orgies was not for him and so he went back to his regular life.

It's fun how the director used the ORGY to depict the various loneliness beneath the surface of the community. It's such a niche genre, I doubt a lot of people will like or understand. But personally, I love this.
The psychedelic effect of the lighting, the disorientation of clip sequencing, the lack of conclusion in each story that plays with your mind which adds more to the realism... The awkwardness, the confusion... it's all so unique and captivating.
You wanna pull away, but you can't because it gives you so much curiosity. Only to leave you hanging on a cliff because that was it. It ends when you start having questions, which are unlikely to be answered.
So you are left sitting there, staring at the screen pondering what you've just watched... refusing to believe that, that was it. It's done...

A fairy tale with no happy endings, just continuous existence... and reeks of poisonous gas instead of pixie dusts...
