I tend to be mostly indifferent about romance although there are times I get tired of overly used tropes, cliches, and anything that seems forced or rushed between characters that just barely met.
But if it involves people trying to ship/pair me with someone, that's where I draw the line. I also get uncomfortable if anyone gets too clingy, make a romantic confession, propose dates, give unnecessary gifts, etc. when we don't know anything about each other yet it becomes fine when this is not done to me irl but in games, etc.
