After We Reorganized Our Family, My Nemesis Became My Stepsister.

[Pure love + exclusive pet] Lin Yanci and Wen Xuyan, from Class 2, Grade 3, are recognized as "competitive partners" in their grade. Their grades are evenly matched and they often compete in academic competitions... But during a family change, Lin Yanci's father and Wen Xuyan's mother reorganized their family. The two people who were originally diametrically opposed on campus unexpectedly became stepsisters living under the same roof. In the days when they get along day and night, Wen Xuyan gradually discovers that Lin Yanci's seemingly strong appearance hides a serious and meticulous side. From the initial awkward run-in, to mutual understanding, to moving forward side by side in studies, and taking care of each other in life, the relationship between the two quietly transformed, and eventually became important partners who could face the pressure of senior year side by side and share their thoughts, leaving a unique mark of growth in their youth.
