Interest Stacks

age gap where both characters are adults. High schoolers are so passé it's all about old farts now <3
My criteria for this list
-my general age gap is at least 10 years, but I have made exceptions for series I like
-the older character needs to look older, I don’t just want 2 identical looking bishies
-the exception to this is non-human or reincarnated beings if I like it enough
-the age gap couple needs to be the main couple in the story
-The younger character needs to be at least college aged, or older. I don’t want HS characters even if they are of age
