Supposed to Be the Stand-In Queen, but Ended Up in a Forced Romance?!

Read Supposed to Be the Stand-In Queen, but Ended Up in a Forced Romance?! / 当て馬王妃のはずなのに、強制溺愛ルートって!?
Catherine was indignant at the incompetence of Queen Catherine, a minor character in a novel she happened to be reading who had the same name as her. But suddenly, she found herself reincarnated as that very Queen Catherine. Although Queen Catherine had entered a political marriage with the king, she was treated coldly despite her status as queen, and in the end, the heroine stole her husband away—a tragic fate for a background character. Not wanting to be used as a stepping stone for the heroine just as the scenario dictated, Catherine began distancing herself from her husband, King Sylas. However, for some reason, Sylas took an interest in her and started closing the gap instead. To make matters worse, Sylas looked exactly like Jason, the classmate who had constantly bullied her before her reincarnation. Overwhelmed by Sylas’s ever-intensifying wave of affection, Catherine found herself flustered. On top of that, the jealous heroine began scheming to set Catherine up… She was supposed to have reincarnated as a minor character in a novel, but somehow the story is straying further and further from the original plot!?
