~I shortened the title but you probably get it~
I'm looking for a manga with a main character (and overall plot line I guess) like Is it Wrong to Try to Pick Up Girls in a Dungeon. It doesn't need to be some crazy harem like this one (that is not really what I like it for) but I do like it when there's romance.
I really like how the main character is super quick at getting good at dungeoning, also how everyone gets really interested in what's making him so strong. Also he's secret backstory~~~ (from the last episode of the anime?) Also I did say I was looking for a manga above but it's fine if it's a webtoon, manhwa or manhua I just don't want to read something that is only a light novel. No offense to light novels but I find manga and the like easier to find and catch up to and stuff, sorry~
~I almost forgot, I don't read yaoi or yuri either~
