The Moonlight White Is Breaking Up Again [Quick Transmigration]

Her mission is to date the male lead, then quickly break up with him for one reason or another and make way for the female lead, so they can live happily ever after. She thought it would be easy, but somehow a few bugs always crop up during the breakup... When she was supposed to dump her poor student boyfriend for being broke, he revealed on the spot that he was secretly a rich heir? When she was supposed to save her own skin by shoving her sickly fiancé in front of a blade, he charged out and turned the tables, wiping out the whole enemy team? When she was supposed to abandon her disciple for the Demon Emperor, who had captured her heart, the Demon Emperor took off his mask to reveal a face exactly like her disciple's?
