I only know the path I played was cockblocking Thaddeus, which Evelyn goes on to thank us (MC) for stopping her from making a mistake she would have regretted. Then her romance path goes cold until about halfway through the game and the MC has to get farther in the story/train his magic ability, to where he gains the info he needs to pursue romance with her. At that point you find out all about her feelings for the MC, why she never acted on them sooner (traumatic family secret), and her renewed pledge to only want to be with the MC going forward.
