If you have read 19 DAYS a Chinese Manhua about daily lives of two close friends with a weird bond was also chapters that didn't link up and comedic,after loads if chapters writer took it seriously abd made 2 couples out of that so there is always a chance
I don't think it's actually set to be romantic, and if the mc ends up with a guy, it'd be probably the end of the manga, coz the whole point of the story is him avoiding all flags.
There is Gekkan Shoujo Nozaki-kun too, some ships are sailing and the comedy gag keeps going.
I mean I wish yaoi on him as much as anyone, but it does seem unlikely. No matter how good a ship gets, this is a comedy manga where the chapters don't link together too closely, so I don't think it would switch to romance, as it would undermine the character and the story structure. But maybe the author will be able to write a romantic interest that is as absurd as the mc, so the vibe of the story won't change? If that's the case, I do think that so far the psychic is the best option, as he doesn't really like the mc yet, and thinks this whole bl thing is absurd.
