After Becoming a Mistress, I Started HE with My Mortal Enemy.

[Two male protagonists + double cleanliness + campus + falling in love and killing each other + HE] [Sunny and cheerful, occasionally poisonous, x cool to the outside and gentle to the inside, plush control attack] Because of an incident in high school, Bai Xingyan unilaterally regarded a certain student union president as a thorn in his side and wanted to compete with him everywhere. Finally, with his unremitting efforts, he was admitted to the same university as Fu Yunli with second place. Bai Xingyan:... Caught off guard, he ended up living in the same dormitory again. On his eighteenth birthday, after Bai Xingyan drank a glass of wine, he not only ate and drank, but also cared for people. After he sobered up and went to bed, Bai Xingyan sat at his desk, scrambling for life and death, vowing to let his enemy know how powerful he was. Suddenly his field of vision became lower, and he turned into a little three-flowered flower. When he looked up, he saw his arch-rival in disheveled clothes, staring at him with scorching eyes. Bai Xingyan cursed for a while because his rival couldn't understand cat talk. Under Bai Xingyan's constant verbal attack, Fu Yunli was finally trampled under his feet, and he lived a life of being pampered by the shit shoveling officer... But who can guarantee that there will be no changes in the future? Crazy Fu's father brought Fu Yunli into a mysterious paradise, and Fu Yunli's life experience was revealed step by step. How will the collision between demons and humans end? Note: Gong can understand Shou's cat language.
