Paohui Gongzhu Xiang Gou Dao Zuìhou
Trying to escape an arranged marriage, the heroine fell into the lake due to a miscalculation of a math problem, and passed through to the body of the former princess Mu Yunkai as she was being hunted down.
According to the world system, if she can seduce all the handsome men in this world and max out their love scores, she'll be able to return to her original world for another chance at life!
She thought this would be a fun isekai romp with lots of pretty boys, but why do all of them seem to want... to kill her?
