Yeaaah I don't think I'm gonna keep reading this one.
It's not relatable to me as I'd rather be called a weirdo than be ashamed of stuff I love, no matter my gender or my age.
And all those characters being judgemental are just pissing me off rather than making feel sorry for the MC, wish is probably the main purpose of the story - make you feel sorry for him to understand him and be more open minded irl maybe or relate to him/find him cute, not working for me. And if it's pissing me off more than it entertains me, better to let go.
Perhaps it gets better later, all the people around him might become more open minded, but it's probably going to take time, if this isn't just going to keep the same formula at making him a "middle aged man who likes cute things and who gets better at hiding it thanks to one or two other closeted cute-things-lover dudes".
A pity, this would have been actually nice and cute if it had been handled better imo.
