To clear up some misinformation here. They are not canonically gay, you could assume that they are somewhat romantic—yes—however, it is not stated explicitly as for now. Geunseo has never mentioned the fact that their genre is BL light as well, I hope OP could double check before commenting in the future.
Thank you for your concern! Idk which side of the fandom you are at but I was half joking answering those questions (If you didn't notice lol). And I never said that "bl light is the genre," to correct my comment saying "author mentioned that the novel is bl light" this is because of the fact that when the time the novel was still ongoing a lot of fans were already shipping the characters and the author did mention that they're aware of that so what did the author did? More fan service for bl fans that's why I specifically used "bl light" as the term ( ̄∇ ̄")
They're so gay that even though manhwa ver is literally censoring a lot, you can't help but notice cause of their chemistry hihi
