I dig how assertive transfer girl is... BUT at the same time, the MC has got to be brain dead if he thinks the ex-Fiancee girl, who cooks him dinner, talks cutesy to him, and Demands physical affection from him, isn't openly displaying romantic feelings directly at him.
She's basically confessed without words, and I don't see how this can write around that, and make them turn into misunderstandings, like it did with the Gal Heroine.
