This one has kinda feel of bromance not sure what to call it but its good

personally i don't like the genres mixed up. adventure/op mc is a whole other world from BL for me.
and in case you haven't noticed 98% of these kinds of stories are actually written by straight guys so if you find something good with BL in it, that would be so very much rare. guys sometimes add bromance for the sake of the female readers tho like this one...give it a try:

I'm sorry but is it just me that wants a manga like this but a little bit gay. Like the Mc is gay(or have shounen Ai/bromance) or a manga where the girls arnt well like this. But I really do like the manga
