It's not biphobia. Thinking so is ridiculous. Try to understand MC's POV.
Imagine being a gay guy (with homophobia trauma) who starts having se* with a man who clearly said he never had exeperience with a guy before (ntm that he found straight por* in his room at some point). From the begining of the relationship, ML clearly displays signs of having no care in world. He looked like he only stayed 'cause MC cooked and warmed his bed (he even helped him clean his house and did his laundry). Wouldn't you feel insecure if you were in his place? the ML looked like he could leave the moment he got bored. MC knows better than anyone how hard it is to be gay in a conservative society. So why would a man who could have a relationship with a woman stick around for long, much less fall in love with him? I wouldn't have believed ML either. A guy who confesses out of the blue, only a month after meeting you and without showing it is weird. What did he really do to get MC's affection? NOTHING.
How is that biphobic? they didn't display their hate towards "bi people" at all (they never ever mentioned it).
Se*uality is not binary, it's a spectrum. You can be curious and try stuff without being able to be in a romantic relationship with the people you sleep with. MC was right to be cautious. Just 'cause you can get it up with a guy doesn't mean you can love him. OR even be able to resist the stigma around your relationship.
Okay this is cute but GOD do I hate the trope of gay mc pushing away “straight” ml and invalidating his feelings even tho he’s standing there confessing to him, like who cares if he’s only liked women so far it means absolutely nothing,
can he get it up with you? Solid yes, is he wanting a romantic relationship with you besides the sex? Yes, SO WHAT THE HELL IS WRONG WITH YOUR BRAIN TO TELL HIM HES STRAIGHT AND NOT ACTUALLY IN LOVE WITH YOU, I’d literally be so pissed if someone tried to tell ME how I feel I’d say ok cool then bye this shit isn’t worth it, “I don’t believe you you’re lying” WHATS THE END GOAL OF THE LIE? BEING IN A ROMANTIC RELATIONSHIP WITH YOU? WHY DO TOU THINK HE WANTS A ROMANTIC RELATIONSHIP WITH YOU, USE YOUR BRAIN FOR A SECOND
And the top having to explain himself and give his whole backstory and explain why he likes him to make him believe it but the mc is allowed to simply like him and be believed with no reasoning and explanation? Even tho they know the same amount of info about each other but it’s enough for mc to have feelings but not enough for ml??? I DONT GET IT, I HATE THIS TROPE UGHHH
