Shift! The Side-Character Heroine

She intended to get herself fully informed of her situation whenever she finds herself in another random story, courtesy of the Two Dimensional Gate, no matter how boring, awful, or distasteful the work was to her.

Like "Pure Romance", under normal circumstances, Zhao Youyue would never read such an erotic, school-based harem manga. However, since she has traveled into this world, she has committed the whole story to memory with all her heart. She believed that understanding the plot is vital if she wants to make things work.

It was also probably due to her preference for the endless, survival type dimension-traveling 'Isekai' novels. These novels have always stressed one thing – knowledge is power. Protagonists would often strive to learn as much as they possibly can about the new, strange worlds they find themselves in.
