Wow, I'm surprisingly pleased by the answer that I got so far! 
I'm aware of the fact that some people just ship any character that shares the same panel/screen if they are two hot/cute guys, it's funny, it's almost like a meme, but it's real, sometimes is because those characters have legit chemistry and sometimes is because they just look good together.
I'm also aware of the fact that some people only want to see some action between male characters, but I don't think that it would fit in my story, at least is not confirmed yet, I mean, maybe those guys do some action because they are horny, but that doesn't mean that they are in love, it's just the heat of the moment, they still have to figure out the emotional part, but all depends if it's relevant to the plot, if it doesn't, the scene will be completely omitted.
Another thing is that one of the characters appears from the beginning while the partner appears a few chapters later as a flashback and then he makes his physical debut after some episodes, so maybe he doesn't count as part of the main cast for not being present for so long.
But something that I noticed too it's interesting because it seems that some people believe that I would change the story in order to please some demographic, well it may look like that's the idea, but that will ruin my story completely with too many forced situations. I prefer to analyze the character's behavior and the situation that they are involved so I can see what would come next.
Some BL and Yaoi do that, I guess because they just have the characters and they don't have nothing else to do with them, so the writers are like "well, let's have some fun with them for a while" and if the writer has a larger cast, then will be all different ways to explore the same situation with "different" personalities.
One curiosity that I want to share about the MC: he has a mom, a dad, and his future boyfriend, so this could be one of the few times that will be exploring a full family interaction because all those characters are relevant for the plot. In a fantasy world.
