Damnit... It's going through the same stereotypical trope... I was hoping it wouldn't.
Main protagonist makes a friend at the school she's in then slowly starts to show a love interest then out of nowhere a transfer student shows up claiming to be a childhood friend it just makes things more difficult then at the end she's going to have to choose between either one of them yadda yadda yadda
This is an annoying love story trope
