i know the plot (the villainess suddenly breaks up with the ml after being clingy and then falls for her after that) is too cliché but it's actually realistic (i can't remember the proper term). the ml thought that it was unusual given that the fl used to be head over heels with him and then suddenly the feelings fade away. ofc you'll take interest in that and find out what happened but since the fl suddenly had a different personality, all bubbly and stuff like that, he would fall for that
