The male lead thought the original Loraine liked him, which never happened, so she needed to get out of the party already to avoid further misunderstandings with the male lead.
Who knows what kind of scheme he was planning to do earlier?
After all, he tried to approach her at the party while there were other people around.
Meaning he would declare it there and then that he had no feelings for her.
In that way, Loraine would seem like she had been avidly pursuing him, and it was causing him trouble, which was why he had to say it there even if it was in front of other people.
'Heh. In your face. I will not allow that to happen, bast*rd!'
She could not possibly allow her most hated character in this story to embarrass her here.
