Romance

Not really a romance

Straight omegaverse??
No r@pe at the first whiff of omega pheromones??;!;,!!,:& (I mean only alphas can control themselves but )
Reverse harem

An alien wants to take over the earth and finds that love is the most common weakness humans hence he kidnaps a human for them to betray earth

Girl one day turns invisible, somehow later on she is able to control this quirk, and decides to stalk her childhood friend because she is too shy to talk to him after being teased about their relationship when they were younger.
The girl is super annoying and actually stalking him with an ahegeo (that sexual face) it’s really gross especially (spoiler but not really) he can see and hear her talking sexual stuff about him n actually following him back to his house
