Justification: "They call him Straight Larry and they're not wrong but I see differently. This guy constantly chases and thirsts over women and none of his relationships with them ever stick. People in the fandom dislike him for that reason, especially when he got flanderized in Trials and Tribulations into more of a shitty womanizer instead of the well meaning hetero dumbass (affectionate) he was in the first game.
Honestly, Larry's life would be so much better if he realised he didn't need to constantly chase woman and force himself into an amatonormativity relationship with them. He found his passion as a surprisingly good artist, and eventually becomes an acclaimed picture book author and I think he would be happier if he just focused on his artworks. Or at the very least, he would not get into as many problems if he stopped pursuing every woman he has feelings for.
And yes, in terms of personal headcanons, I see him as Arospec Het. :]"
We have moved past Maya and Franziska wingmanning narumitsu as a society. They would not fucking do that. We need to realise the truth which is that Larry and Gumshoe would try to wingman them and only succeed through failure
