I'd have been more surprised if he wasn't honestly, the dude always gave off "I'm not gay, I just sleep with dudes to get off cause it's easier" vibes. Also, bisexual tops seem to be the new trend in BL and given that BJ Alex was also Bi the author has history with that trope.
With the way he was tearing ol boy up, I definitely thought he was just either gay or one of those “I don’t do labels” kind of men. I definitely agree with the bisexual top thing being a trope, despite us never getting any slides of them actually having sex with a female physique.
I can’t believe he’s into girls too lol I thought dude was gay asl
