"Isekai GL/BL with summoning trope" The rebirth ones are a little... off-putting to me. Something like, "Money makes the (Other) World Go Round: The Corporate S*ave Dragged into the Saint Summoning", it doesn't matter if it is smut or Shou/nen/jo Ai. Not particular about the MC's personality either, they can be dumb as rocks, dense as a harem protagonist, horny or contrived scum.
