Man, stop it with the LGBT talk. Many otaku hobbies have girly shit in it, but they're not gay. Many like dollfies, fumos, nesoberi, but they're not gay. I have dollfies too and like cute clothes for them, but I still like girls. Iirc in one chapter our mc did thought about political marriage but decided to not think about it. Same with the prince when it's obvious he is flirting.
Made me look back to previous chapters, ch2 page 26 should be your answer what the mc thinks.
