This one seme is rough around the edges at first, but a good guy:

Note that this has themes of C#ile Prostitution/Pedophilia and many other things that are just immoral and unpleasant.
It does not start off with those themes but explores MC's sexuality first and some events throughout his coming out to his family, all themes said in the first sentence will start appearing after MC meets ML.
ML is overall a great fucking dude bro, He's someone i'd picture of if you think of the word "Husband" or "House Husband".
Got any yaoi/ romance manga with a rather “dark” world setting (something like the Mc having a shitty live because of mental health, debt etc) BUT instead of the Ml being a toxic Asshole who makes everything worse, he’s a super Wood Green green flag?
(If there’s a 2nd Ml, it doesn’t matter wether this one is an asshole or not cause he won’t end up with the mc)
