Try baetodi's works. Personally I like this one more https://www.mangago.zone/read-manga/on_the_lake_where_the_waves_reach/ than ghost of paradise https://www.mangago.zone/read-manga/ghost_of_paradise/
Form of sympathy is rather long but it's a great read https://www.mangago.zone/read-manga/form_of_sympathy/
If you're fine with fantasy & dungeon conquest, try trace of the sun https://www.mangago.zone/read-manga/a_trace_of_the_wonder/ or death delayed https://www.mangago.zone/read-manga/death_delayed_for_a_short_time_because_of_the_will/ but this one is still on going though
Thanks a lot!!!
Guys, can y'all recommend stories (bl) with miserable characters? I'm talking about depressed, dysfunctional adults and kinda messed up in the head
