Good luck finding something decent. In my own experience, reading BL is a roll of the dice. Sometimes you find something good and other times it's literally rape framed as "cute/hot". Anyways, I recommend Sandu, Sokuochi Yarichin Yankee, Ake Nure Goyou ni Furu Yuki wa, and mostly any doujin by 3745house :)
https://www.mangago.zone/read-manga/the_honest_life_of_a_game_studio/ these guys talk about their relationship in between adventuring.
I just want to finally read something where the characters develop the relationship first and then actually do stuff with consent and shit. Not just the usual stuff I see.
