Imagine you are with your partner on a date ,and someone comes over to you two and starts declaring how they have stalked your partner for a long time,thus they know them better and are more "deserving" of being in a relationship with them. Not only that , they start shaming you and the way you show your affection for your partner !
What do you think would be the best way to react ?
Because that kind of annoying bitch is this girl and I am surprised that nobody yet has told her to fuck off.
Don't like this new girl. Especially since it seems like she's just being extremely rude. Actually, disgusting is a better word. Always hate reading about these types in novels, manga, and anime where someone tries to say "I'm the better choice," you don't get to make that decision.
