I know right ??? and she seems to like byul genuinely, it's just the fact that byul isn't interested in her at all, even from the start, and if I remember correctly, she "dumped" him bcz byul aren't the "perfect boyfriend" (in the first place, I think he accepted her bcz he didn't want to hurt her feeling) so her reaction is understandable, like imagine your partner says "I forgot I had a girlfriend"
Thats a high school girl so of course shes gonna act like that, you guys need to chill. I saw every site that she has been getting unnecessary hate everywhere, my girl doesnt deserve all that hate.
