@PTRB Oh, I don't deny that it's in her character, but that doesn't make it any less unpleasant to witness or to make me want to forgive her for her actions. I hope she suffers miserably for this decision.
@Natureboy But, he's not her friend and she personally does not know him from a hill of beans, nor is he her boyfriend's friend so, for her to choose to go off to his house to watch a movie, leaving her boyfriend behind, is mind-bogglingly stupid. I just can't emphasize just how mind-bogglingly stupid that is. In the typical manga, when they are alone in his room, the guy will then try to force himself on the girl. She should know this considering what she reads. Wanting to know more about her boyfriend from someone else, instead of from the boyfriend himself, is such overused, clichéd storytelling that is only used to create unnecessary drama. Yawn.
